Final answer:
The question asks for a program that reads an integer representing the number of words in a list, the words themselves, and a character, and then prints each word from the list that contains the character at least once. A sample Python script has been provided to illustrate how this can be achieved by iterating through the list and checking for the presence of the character in each word.
Explanation:
To create a program that reads an integer, a list of words, and a character, where the integer indicates the number of words in the list, and the output displays every word containing the specified character at least once, you would typically use a programming language like Python. The task involves iterating through the list of words and checking if each word contains the character. Here is a simple example in Python:
# Read the integerThis script prompts the user to input the number of words, the words themselves, and the character to search for. It then prints out any word that contains the character.
Statistics are often calculated with varying amounts of input data. Write a program that takes any number of integers as input, and outputs the average and max.
Ex: If the input is:
15 20 0 5
the output is:
10 20
Answer:
Python
nums = [int (i) for i in input().split()]
max_sorted = sorted(nums)
avg = sum(nums) // len(nums)
print(avg, max_sorted [-1])
Explanation:
First you want input and to split it. so they can add numbers like this 12 13 15 16
Then you sort it which will sort the list so that the greatest value is at the end.
you define average as avg
Finally you print the average and the end of the sorted list which will be the max value!

Create a java program that has a code file with main() in it and another code file with a separate class. You will be creating objects of the class in the running program, just as the chapter example creates objects of the Account class. Your system creates a registration bills for the billing part of a college. Create a class called Registration that holds the following information: first name, last name, number of credits, additional fees. The class should have all the gets and sets and also have a method to show the bill (with their name and the total which is 70 per credit + the additional fees) to the student. (You cannot have spaces in variable names. So you might call the first one firstName, first_name, fname or any other appropriate and legal variable name. The write up above is telling you the information to be stored in English, not java). Create 2 objects of Registration in your main code class and display the bills to the user with the method that shows the bill. Then add 3 credit hours to the first one, and subtract 3 credit hours from the second one and show the bills for both to the user again. (Hint: use the get) to read it out to a variable, add 3 (or subtract 3 for the second on), then use the set0 to store it back in replacing the old number of credit hours in the object.) (You can hard code the names, credit hours, and additional hours you are storing in the 2 Registration objects or ask the used for them with a Scanner. Either way is fine. It is perfectly all right from a grading standpoint to just give it test values like the chapter example does).
Answer:
public class Registration {
private String fname;
private String lname;
private int noCredits;
private double additionalFee;
public Registration(String fname, String lname, int noCredits, double additionalFee) {
this.fname = fname;
this.lname = lname;
this.noCredits = noCredits;
this.additionalFee = additionalFee;
}
public String getFname() {
return fname;
}
public void setFname(String fname) {
this.fname = fname;
}
public String getLname() {
return lname;
}
public void setLname(String lname) {
this.lname = lname;
}
public int getNoCredits() {
return noCredits;
}
public void setNoCredits(int noCredits) {
this.noCredits = noCredits;
}
public double getAdditionalFee() {
return additionalFee;
}
public void setAdditionalFee(double additionalFee) {
this.additionalFee = additionalFee;
}
public void showBill(){
System.out.println("The bill for "+fname+ " "+lname+ " is "+(70*noCredits+additionalFee));
}

Explanation:
A store sells widgets at 25 cents each for small orders or at 20 cents each for orders of 100 or more. Write a program that requests the number of widgets ordered and displays the total cost. (write the python program and after confirming it works, copy and paste the program code below)
Answer:
widgets=float(input("Enter number of widgets you want to buy"))
if widgets<0:
print("Can't compute negative number")
else:
if widgets<100:
cost=widgets*25
else:
cost=widgets*20
print("The total cost of widgets is", cost,"cents")
Explanation:
First I made a variable called widgets to take input of the number of widgets the customer wants to buy. I use the first comditional statement to test if the number of items typed in is not less than zero.
The else statement computed the prices of widgets based on number of widgets greater than zero.
Another conditional statement to check if the widgets is lower that 100 or greater. The cost represents the total amount, in terms of cost it will take for some nuber of widgets.
The last line prints the total cost and some statments
Final answer:
A Python program to calculate the total cost of widgets takes the number of widgets as input, determines the price per widget based on order quantity, and calculates the total cost.
Explanation:
Python Program for Calculating Total Cost of Widgets
If a store sells widgets at 25 cents each for small orders or 20 cents each for orders of 100 or more, the following Python program will calculate the total cost based on the number of widgets ordered:
# Ask the user for the number of widgets ordered
number_of_widgets = int(input("Enter the number of widgets you want to order: "))
# Determine the price per widget based on the quantity
if number_of_widgets < 100:
price_per_widget = 0.25
else:
price_per_widget = 0.20
# Calculate the total cost
total_cost = number_of_widgets * price_per_widget
# Display the total cost
print(f"The total cost for {number_of_widgets} widgets at ${price_per_widget:.2f} each is: ${total_cost:.2f}")
This program first asks the user to enter the quantity of widgets they wish to order. It then uses a conditional statement to determine the price per widget based on the quantity. Finally, it calculates the total cost and prints the result.

Your Community Supported Agriculture (CSA) farm delivers a box of fresh fruits and vegetables to your house once a week. For this Programming Project, define the class Box Of Produce that contains exactly three bundles of fruits or vegetables. You can represent the fruits or vegetables as an array of type string. Add accessor and mutator functions to get or set the fruits or vegetables stored in the array. Also write an output function that displays the complete contents of the box on the console.
Next, write a main function that creates a Box Of Produce with three items randomly selected from this list:
Broccoli Tomato Kiwi Kale Tomatillo.
This list should be stored in a text file that is read in by your program. For now you can assume that the list contains exactly five types of fruits or vegetables. Do not worry if your program randomly selects duplicate produce for the three items.
Next, the main function should display the contents of the box and allow the user to substitute any one of the five possible fruits or vegetables for any of the fruits or vegetables selected for the box.
After the user is done with substitutions output the final contents of the box to be delivered.
Answer:
C++.
Explanation:
class BoxOfProduce {

In Programming Exercise 2, the class dateType was designed and implemented to keep track of a date, but it has very limited operations. Redefine the class dateType so that it can perform the following operations on a date, in addition to the operations already defined: a. Set the month. b. Set the day. c. Set the year. d. Return the month. e. Return the day. f. Return the year. g. Test whether the year is a leap year. h. Return the number of days in the month. For example, if the date is 3-12-2011, the number of days to be returned is 31 because there are 31 days in March. i. Return the number of days passed in the year. For example, if the date is 3-18-2011, the number of days passed in the year is 77. Note that the number of days returned also includes the current day. j. Return the number of days remaining in the year. For example, if the date is 3-18-2011, the number of days remaining in the year is 288. k. Calculate the new date by adding a fixed number of days to the date. For example, if the date is 3-18-2011 and the days to be added are 25, the new date is 4-12-2011.
Answer:
Java class is given below
Explanation:
class Date{
private int date;
private int month;
private int year;
public Date(){}
public Date(int date,int month, int year){
this.date= date;
this.month = month;
this.year = year;
}
public void setDate(int date){
this.date = date;
}
public void setMonth(int month){
this.month = month;
}
public void setYear(int year){
this.year = year;
}
public int getDate(){
return date;
}
public int getMonth(){
return month;
}
public int getYear(){
return year;
}
public boolean isLeap(int year){
return year%4==0
}
}
To redefine the dateType class and add the requested operations, modify the class and include methods like setMonth, setDay, setYear, getMonth, getDay, getYear, isLeapYear, daysInMonth, daysPassedInYear, daysRemainingInYear, and addDays.
Explanation:Redesigning the dateType ClassTo redefine the dateType class and add the requested operations, you can modify the existing class and include the following methods:
setMonth(int m): Set the month of the date.setDay(int d): Set the day of the date.setYear(int y): Set the year of the date.getMonth(): Return the month of the date.getDay(): Return the day of the date.getYear(): Return the year of the date.isLeapYear(): Test whether the year is a leap year.daysInMonth(): Return the number of days in the month.daysPassedInYear(): Return the number of days passed in the year.daysRemainingInYear(): Return the number of days remaining in the year.addDays(int numDays): Calculate the new date by adding a fixed number of days to the date.By implementing these methods, you can enhance the functionality of the dateType class to perform all the requested operations.

A startup company is using an excel spreadsheet to keep track of the billable hours that each employee spends on a project. As you can see, they are not data modelers. They would like to convert the spreadsheet into a database that they can use as a back end for a time keeping application. The column names of the spreadsheet are shown below:
Project ID Project Name Project Manager Project Manager Location Employee ID
Employee Name Employee Location Title Hourly Rate Billable Hours
Draw a dependency diagram for the schema and identify all dependencies, including all partial and transitive dependencies. You can assume that the table does not contain repeating groups. Here are the field descriptions:
Project ID – the identifier for the project
Project Name – the name of the project
Project Manager – the name of the project manager for a project, projects can have more than one project manager
Project Manager Location – location of the project manager
Employee ID – the identification number for an employee
Employee Name – the name of an employee
Employee Location – the location of an employee
Title – the position title for the employee
Hourly Rate – the rate that is charged to the project sponsor based on the position of the employee
Hours worked – the number of billable hours that an employee has charged to a project
2. Remove all partial and transitive dependencies and draw a new set of relations in third normal form. Put your thinking cap on because there are some obvious data management pitfalls associated with the above relation.
3. Draw the entity relationship diagram.
4. Based on your ERD, draw the physical data model including tables, attributes, data types, primary keys, and foreign keys.
Answer:
Hello there! There are 4 parts to this question, all regarding relational database concepts.
Explanation:
Parts 1, 2, 3, 4 are drawn in attachments. For Part 4, the "foreign keys" would be the id fields of the joining table, and the "primary keys" are the IDs of the table itself. Data types are "integer" for ID, "string" for text columns like Name and Location, and "Decimal" for Hourly rate in the Timesheet table. Note that we can further simplify the erd from the one constructed earlier in part 3 to remove the Project Manager model and instead add a Project Manager "boolean" flag in the Employee table since a Project Manager is also an Employee.
John downloaded Alten Cleaner, a program that poses as a computer registry cleaner, on his computer. Once he installed the program on his computer, the program illegitimately gained access to John’s passwords and credit card information. In this scenario, it is evident that John was a victim of _____.
a. spoofing
b. phishing
c. baiting
d. pharming
Answer:
a. spoofing
Explanation:
In this context, it is clear that John was a victim of spoofing. In information security, spoofing occurs when a person or program identifies itself as another by falsifying data, in order to gain an illegitimate advantage. In this example, the program identified itself as a computer registry cleaner in order to gain access to John's passwords and credit card information. Spoofing can apply to emails, phone calls, websites, IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.
Final answer:
John was a victim of phishing, where his personal information, such as passwords and credit card details, was fraudulently obtained through a deceptive program. Phishing is a common method utilized by hackers to exploit human vulnerabilities, and the enforcement against these computer crimes can be challenging due to limited resources.
Explanation:
In the scenario described, John downloaded a program masquerading as a computer registry cleaner which then illegitimately gained access to his passwords and credit card information. John was a victim of phishing. This type of attack involves fraudulently obtaining personal information by posing as a legitimate entity.
Phishers use various tactics, such as sending emails or messages that seem trustworthy, to trick individuals into revealing sensitive information.
Hackers use phishing as a method to break into systems and lure victims into handing over confidential data. The rise of phishing attacks has become a significant issue, as cybercriminals continue to find new ways to target unsuspecting users and exploit human vulnerabilities for financial gain or identity theft.
Unfortunately, as pointed out by Cameron (2002), the enforcement of computer crimes is often hampered by limited resources and the ability of criminals to use technology to their advantage. Personal vigilance and caution when engaging with unfamiliar or unsolicited digital content are key to protecting oneself from these kinds of threats.

Answer:
Answer explained below. The remaining part of the question is incomplete
Explanation:
The concepts of confidentiality, integrity, and availability (C-I-A) can be explained in following given points.
1) Confidentiality: Its basically refer to the confidentiality of the information. Here we can think about the protection of the information from unauthorized person. Confidentiality enuser that at what level your information is secured and no unauthorized access will be done to the information. For maintaining the confidentiality, we can use various encryption methods. The main concept of confidentiality is to enforce various techniques like encryption, file permissions and access control to restrict access to important information.
2) Integrity: Integrity of the information refer to the unwanted modification of the information. Integrity of the data as well as the information should be maintained and only the autorized person can access as well as modify the information. For enforcing the integrity, we can implement various hashing techniques on information.
3) Availability: Availability refers to the availability of the information, when ever an autorized person requests for the information. High availability of the information should occur, so that any autorized person can access it, when ever its required. For high availability, we can create backup as well as replicate the data across the geo sites.
Seven domains of a typical IT infrastructure are given below:
1) User Domain: Its refer to the group of users as well as the person who access the information systems.
2) LAN Domain: Refer to the local area network, where various computers are connected to each other.
3) Workstation Domain: The area is called workstation, where various users connect to the IT infrastructure.
4) WAN and LAN link domain: Refer to the connection of local area network to wide area network.
5) WAN domain: Refer to the wide area network, connection of computers in large area.
6) Storage Domain: Refer to the storage, where we store the data.
7) Remote Access Domain: Refer to the domain where mobile user can access the local as well as wide network remotely.
Given a 3 Gbps link with TCP applications A, B, and C. Application A has 25 TCP connections to a remote web server Application B has 4 TCP connection to a mail server Application C has 3 TCP connections to a remote web server. According to TCP "fairness", during times when all connections are transmitting, how much bandwidth should Application C have?
(The answer is 281.3 Mbps, but please show me how.)
Answer:
Application C has 281.3 Mbps.
Explanation:
The TCP A, B and C connections all share a 3Gbps link.
Where 3Gbps is the bandwidth ( the number of bits or bytes the link can transmit in one second) and is equivalent to 3,000,000,000 bytes.
Connection on TCP A = 25,
Connection on TCP B = 4,
Connection on TCP C = 3,
The total number of connections are = 25 + 4 + 3 = 32.
When all connections are using the link,
The TCP C bandwidth is = (3/32) x 3,000,000,000 bytes.
= 0.09375 x 3,000,000,000
= 281250000 bytes.
= 281.25 Mbps or 281.3 Mbps.

What does Lowenstam mean by the "interactive" model as a way of describing the relationship between images and texts? Explain.
Answer:
What does Lowenstam mean by the "interactive" model as a way of describing the relationship between images and texts? Explain.
Explanation:
The Lowenstam intercative model tries to explain the relationship between myth, poetry and art in the Homeric poems and the epic stories, stating that archaic Greek vases painters were representing, with their own artistic features, not thinking themselves as to be the illustrators of the texts the way we inherited them, but in the way they interpreted them.
1.) You are a digital forensic examiner and have been asked to examine a hard drive for potential evidence. Give examples of how the hard drive (or the data on it) could be used as (or lead to the presentation of) all four types of evidence in court; testimonial, real, documentary, and demonstrative. If you do not believe one or more of the types of evidence would be included, explain why not.
Answer & Explanation:
The hard drive could contain some type of reports which might prove to be the evidence of some bad guys involved. Some real evidence such as images or documents related to the crime committed such as corruption-related property papers details of bank accounts along with a possibility that it may also contain a video recording which may prove as evidence. so there shouldn't be any demonstrative proof which can present there by having a hard drive and can be used as evidence in the court.
Section 1.10 cites as a pitfall the utilization of a subset of the performance equation as a performance metric. To illustrate this, consider the following two processors. P1 has a clock rate of 4 GHz, average CPI of 0.9, and requires the execution of 5.0E9 instructions. P2 has a clock rate of 3 GHz, an average CPI of 0.75, and requires the execution of 1.0E9 instructions(a)One usual fallacy is to consider the computer with the largest clock rate as having the largest performance. Check if this is true for P1 and P2. (5pts)
(b)Another fallacy is to consider that the processor executing the largest number of instructions will need a larger CPU time. Considering that processor P1 is executing a sequence of 1.0E9 instructions and that the CPI of processors P1 and P2 do not change, determine the number of instructions that P2 can execute in the same time that P1 needs to execute 1.0E9 instructions. (5pts)
(c)A common fallacy is to use MIPS (millions of instructions per second) to compare the performance of two different processors, and consider that the processor with the largest MIPS has the largest performance. Check if this is true for P1 and P2. (5pts)
(d)Another common performance figure is MFLOPS (millions of floating-point operations per second), defined as
MFLOPS = No. FP operations / (execution time X IE6)
But this figure has the same problems as MIPS. Assume that 40% of instructions executed on both P1 and P2 are floating-point instructions. Find the MFLOPS figures for the processors.

Explanation:
Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text python
To create a program that reverses text and repeats this process, a Python script uses a while loop and input function to read and reverse user input, finishing when 'Quit', 'quit', or 'q' is entered.
Creating a Text Reverse Program in Python
To create a program that reverses a line of text and repeats until the user decides to quit, we need to write a Python script that continuously reads user input and reverses it. The script will terminate when the user enters 'Quit', 'quit', or 'q'. Here is a simple Python program to accomplish this task:
while True:
user_input = input("Enter a line of text (type 'Quit', 'quit', or 'q' to exit): ")
if user_input in ['Quit', 'quit', 'q']:
break
print(user_input[::-1])
This program utilizes a while loop along with an input function to read text from the user. It then checks if the user wants to quit the program. If not, the program uses string slicing to reverse the text and print it out.
Write a function that takes an integer as an argument and returns True if the number is within the range 1 to 555 (not inclusive, i.e. neither 1 nor 555 are in range).
Answer:
The program to this question as follows:
Program:
def Range(n): #defining a method Range and pass variable n as a parameter
if (1<n<555): #if block for check range
return True #return value
else:
return False #return value
n=int(input('Enter the value: ')) #defining variable n and input a value
d=Range(n) #defining variable d and call the method that holds value
print (d) #print value
Output:
Enter the value: 34
True
Explanation:
In the above python code, a function "Range" is defined, which uses a variable n as a parameter, inside the function, the conditional statement is used, inside the if block, if the input value is in the range between 1 to 555. if it is true will return a value that is "True" or it will go to the else part that returns a value "False".
Outside the function, variable n is defined, which uses input function for input the value from the user, and another variable d is defined, that holds function return value and uses print function to print its value.
Calculate the number of hours since the birthdate. Insert your calculation in cell C15. (hint: convert the number of days to number of hours by multiplying the number of days in C14 by 24.)
Final answer:
To calculate the number of hours since a birthdate, multiply the number of days by 24 and insert the result in cell C15.
Explanation:
To calculate the number of hours since the birthdate, you need to first determine the number of days that have passed since that date. Once you have the number of days in cell C14, you multiply it by 24 to convert the number of days to a number of hours. For example, if cell C14 contains 10 days, then you would calculate the hours as follows:
10 days x 24 hours/day = 240 hoursYou would then insert the result, 240 hours, into cell C15 to complete the calculation.
The number of hours since the birthdate is calculated by multiplying the number of days in cell C14 by 24.
ExplanationTo determine the duration in hours since the birthdate, the process involves converting the number of days provided in cell C14 into hours. As there are 24 hours in a day, multiplying the number of days by 24 yields the total number of hours.

Answer:
a. Using 32bit unsigned binary system, x is bigger than y
b. Using 32 bit signed system, x is not bigger than y.
Explanation:
a.
x = (1111 1111 1111 1111 1111 1111 1111 1100)2
y = (0011 1011 1001 1010 1000 1010 0000 0000)2
In an unsigned system all binary digits are used up as the magnitude bits;
First, we need to convert each number to decimal
x = 4294967292 (decimal)
y = 999983616 (decimal)
4294967292 is greater than 999983616
So, x is greater than y (in 32 bit unsigned binary system)
b.
x = (1111 1111 1111 1111 1111 1111 1111 1100)2
y = (0011 1011 1001 1010 1000 1010 0000 0000)2
In a signed system, the most significant bit is used as the signed bit, the remaining bits are used in representing the magnitude bits;
The most significant bit is always the first bit.
0 represents positive (+)
While
1 represents negative (-)
First we need to separate the most significant bit from the magnitude bits.
So x = 1 (111 1111 1111 1111 1111 1111 1111 1100)2
And y = 0 (011 1011 1001 1010 1000 1010 0000 0000)2

BI is an umbrella term that combines architectures, tools, databases, analytical tools, applications, and methodologies. b. BI is a content-free expression, so it means the same thing to all users. c. BI's major objective is to allow access to data (and models) to only IT. d. BI does not help transform data, to information (and knowledge), to decisions and finally to action.
Answer:
architectures, tools, databases, analytical tools, applications, and methodologies
Explanation:
There are several features of business intelligence. It is a content-free expression, which means that it means different things to different people, and not same thing as suggested by Option B. While its major objective is to enable or allow easy access to data, it is not limited to data and IT only as suggested by Option C. Instead it provides managers of businesses with the ability of analysis of data. And finally it helps in the transformation of data to information and to action, which is contrary to the suggestions of Option D. Hence the first option is the only correct option.

Lossless and lossy are the two (2) universally known categories of compression algorithms. Compare the two (2) categories of algorithms, and determine the major advantages and disadvantages of each. Provide one (1) example of a type of data for which each is best suited.
Answer:
The lossy compression method is also known as irreversible compression and is beneficial if the quality of the data is not your priority. It slightly degrades the quality of the file or data but is convenient when one wants to send or store the data. This type of data compression is used for organic data like audio signals and images. The algorithm use in Lossy compression include: Transform coding, DCT, DWT, fractal compression, RSSMS.
The Lossless compression method is also known as reversible compression and is capable of reconstituting the original form of the data. The quality of the data is not compromised. This technique allows a file to restore its original form. Lossless compression can be applied to any file format can improve the performance of the compression ratio. The algorithm use in Lossless compression include: RLW, LZW, Arithmetic encoding, Huffman encoding, Shannon Fano coding.
Advantage of Lossy compression: Lossy compression can achieve a high level of data compression when compared to lossless compression.
Advantage of Lossless compression: Lossless compression doesn’t degrade the quality of data during compression
Disadvantage of Lossy compression: Lossy compression degrades the quality of the data during compression
Disadvantage of Lossless compression: Lossless compression has less data holding capacity when compared to lossy method
Example of type of data for Lossless compression: Text
Example of type of data for Lossy compression: Audio
Explanation:
Answer:
Lossless retains the file size while lossy algorithm discards excess files size or parts.
Explanation:
Compression algorithms are algorithms used to minimise the file size of a large file format. It is handy for maximising available disk space and reduce upload and download time of these files. Lossless and lossy are two types of compression algorithms.
Lossless algorithm is used to compress a file, but yet retains the structure of the original file or data. It is used where an identical file from the original is favourable and is used in archives.
Lossy is the opposite of lossless because it discards excess parts of a file. It is used in compressing audio files like MP3.
The cost to ship a package is a flat fee of 75 cents plus 25 cents per pound.
1. Declare a constant named CENTS_PER_POUND and initialize with 25.
2. Get the shipping weight from user input storing the weight into shipWeightPounds.
3. Using FLAT_FEE_CENTS and CENTS_PER_POUND constants, assign shipCostCents with the cost of shipping a package weighing shipWeightPounds.
Final answer:
To calculate the cost of shipping a package based on weight, you can use the formula: 'shipCostCents' = FLAT_FEE_CENTS + (CENTS_PER_POUND * shipWeightPounds).
Explanation:
To calculate the cost of shipping a package that weighs 'shipWeightPounds', we can use the formula:
'shipCostCents' = FLAT_FEE_CENTS + (CENTS_PER_POUND * shipWeightPounds)
For example, if the flat fee is 75 cents and the weight of the package is 5 pounds, the calculation would be:
shipCostCents = 75 + (25 * 5) = 75 + 125 = 200 cents.
Final answer:
The problem involves calculating the shipping cost using a constant price per pound plus a flat fee. It exemplifies the importance of understanding unit conversions and shipping rate calculations for mailing packages.
Explanation:
The given problem requires creating a simple program that calculates the shipping cost based on the weight of a package. To begin the process:
Declare a constant named CENTS_PER_POUND and initialize it with the value 25 to represent the cost per pound.Prompt the user for the package weight and store this input in a variable named shipWeightPounds.Calculate the shipping cost (shipCostCents) using the FLAT_FEE_CENTS and CENTS_PER_POUND constants. This is done by multiplying the weight of the package by the cost per pound and adding the flat fee.Applying this to a real-world scenario helps understand why it matters. According to the information provided, understanding how to calculate shipping costs based on weight is essential for sending mail. For instance, if you had a package weighing 2 pounds, you would convert the weight to ounces (since there are 16 ounces in a pound), resulting in 32 ounces. Using the shipping rates mentioned (where the first 3 ounces cost $1.95, and each additional ounce costs $0.17), the cost for a 32-ounce package would be calculated as shown by LibreTexts™.
