Cynthia has the choice of taking out a 25-year loan for $155,000 at 4.4%
interest, compounded monthly, or the same loan at 20 years for a higher
monthly payment. If she would pay a total of $100,831 in interest on the 25-
year loan, how much in total would she pay in interest on the 20-year loan?
Answer:
D. Less than $100,831
Step-by-step explanation:
There is an equation for calculating monthly payment:
x = p • r • (1+r)^n / (1+r)^n - 1
It may seem a bit complicated, but let's explain it step by step:
- p is the amount of loan, in this case $155,000
- r is monthly interest rate, in this case (4.4/12) / 100, which is 0.00367
- n is the number of months for paying back, or in this case 20 • 12 = 240
Now that we know all the values, all that's left is to plug them in and solve it on the calculator:
x = 155,000 • 0.00367 • (1.00367^240) / (1.00367^240) - 1
x = $972.27
So, the monthly payment is around $972.3. We now multiply it by the number of months to get total payment:
$973.3 • 240 = $233,352
So, the total amount, loan plus interest, is 233,352 dollars.
To only find amount of interest, we simply subtract loan from total amount:
$233,352 - $155,000 = $78,352
Expression equivalent to 5(3m + n)
Answer:
Step-by-step explanation:
5(3m + n) = 15m + 5n
Final answer:
The expression equivalent to 5(3m + n) is found by applying the distributive property, resulting in 15m + 5n, where the 5 is multiplied by each term inside the parentheses.
Explanation:
The expression 5(3m + n) is an example of the distributive property in algebra. To find an expression equivalent to this, we need to distribute the 5 across the terms inside the parentheses. This means we multiply 5 by each term inside the parentheses.
Multiply 5 by 3m, which gives us 15m.Multiply 5 by n, which gives us 5n.Putting these two results together, the equivalent expression is 15m + 5n. This is a straightforward application of the distributive property, which is a fundamental concept in algebra.

Brainliest for best answer. No stupid answers please!
Answer:
They both have the same slope.
They have different y- intercepts.
They have no solution.
Please let me know, if I am right or wrong. I try my best to give correct answers
Answer:
A
Step-by-step explanation:
The standard equation is
y = mx + c
Where m is the slope and c is the y intercept
The 1st equation y = -2x + 1/4
Comparing with standard equation
the slope m = -2 and c = 1/4
The 2nd equation y = -2x - 1/4
Comparing with standard equation
the slope m = -2 and c = -1/4
To check if it as a solution
y = -2x + 1/4.......(1)
y = -2x - 1/4........(2)
Substracting (2) from (1)
y - y = -2x + 2x + 1/4 + 1/4
No solution since both x and y were eliminated

A train leaves a station and travels north at a speed of 45 mph. Two hours later, a second train leaves on a parallel track and travels north at 75 mph. How far from the station will they meet?
Both trains will meet in 3 hours.
Step-by-step explanation:
Given,
Speed of train A = 45 mph
Distance covered in two hours = 2*45 = 90 miles
Let,
x be the number of hours for both trains.
A(x) = 45x+90
Speed of train B = 75 mph
B(x) = 75x
For same distance;
A(x) = B(x)
[tex]45x+90=75x\\90=75x-45x\\90=30x\\30x=90[/tex]
Dividing both sides by 30
[tex]\frac{30x}{30}=\frac{90}{30}\\x=3[/tex]
Both trains will meet in 3 hours.

The variable x represents the number of long sleeve shirts Nancy bought and the variable y represents the number of short sleeve shirts she bought.
Nancy bought 531 shirts for her business. She bought 2 times as many short sleeve shirts as long sleeve shirts.
How many of each type of shirt did she buy?
Final answer:
Nancy bought 177 long sleeve shirts and 354 short sleeve shirts for her business by solving a system of linear equations based on the provided constraints that she bought a total of 531 shirts and twice as many short sleeve shirts as long sleeve shirts.
Explanation:
The student's question involves solving a system of linear equations to find out how many of each type of shirt Nancy bought for her business. Following the given relationships between long sleeve shirts (x) and short sleeve shirts (y), we understand that Nancy bought a total of 531 shirts and that she bought twice as many short sleeve shirts as long sleeve shirts. The two equations that can represent this scenario are:
Equation 1: x + y = 531
Equation 2: y = 2x
To solve this system, we substitute Equation 2 into Equation 1 to get:
x + 2x = 531
Which simplifies to:
3x = 531
Dividing both sides by 3, we find that:
x = 531 / 3 = 177
Using the value of x to find y from Equation 2, we get:
y = 2 * 177 = 35
Therefore, Nancy bought 177 long sleeve shirts and 354 short sleeve shirts.

Question:
Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large cups for $2.50. If Ashley sold a total of 155 cups of lemonade for $265, how many cups of each did she sell
Answer:
The number of small cups of lemonades is 98
The number of Large cups of lemonades is 57
Step-by-step explanation:
Given:
Cost of small lemonade cups = $1.25
Cost of large Lemonade cups = $2.50
Total number of lemonade cups = 155 cups
The total cost for which the lemonade is sold = $265
To Find:
Number of each types of lemonade sold = ?
Solution:
Let the number of small cups of lemonade sold be x
the number of large cups of lemonade sold be y
Then according to the question,
x+y = 155-----------------------------(1)
Then the amount earned by selling small and large lemonade cups is $265
Then
1.25x+2.50y = 265------------------(2)
From (1)
y = 155-x----------------------------------(3)
Substituting (3) in (2), we get
1.25x+ (155-x)2.50 = 265
1.25 + (387.5 -2.50x) =265
-1.25x + 387.5 = 265
-1.25x= 265 -387.5
-1.25x = -122.5
[tex]x = \frac{-122.5}{-1.25}[/tex]
x= 98--------------------------------(4)
Substituting (4) in (3)
y = 155-98

A typical traffic signal is programmed on a timer so that it is red 50% of the time, green 42% of the time, and yellow 8% of the time. The bulbs for each color are LED and are designed to last 100,000 hours. How many years does each color light last? Give your answer in years and months (rounded to the nearest month). What is the problem asking? What do we know? How did you solve the problem? Explain your steps.
Please answer this question for me
The problem is asking to identify how many years would each color light last. We know that a red light turns on 50% of the time, a green light is 42% of the time, and yellow is 8% of the time. Each light lasts 100,000 hours.
Although this question gives a lot of information, we really don't need the percentages of the lights. They simply are there to throw you off. Each light lasts 100,000 hours. We will use the following conversions:
1 day = 24 hours
1 year = 365 days
100,000 hours divided by 24 hours = 4166.67 days
4166.67 days divided by 365 days = 11.4 years (the 4 is 4 months).

Answer: x=1
Step-by-step explanation:
(X+5)-2(4x-1)=0
(-2•4x) (-2•-1)
X+5-8x+2=0
X-8x+5+2=0
(5+2)=7
X-8x=-7
-7x= -7
X=1
Simplifying the given expression (x +5) -2(4x-1)=0 we get the solution of this expression is x = 1.
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
The given expression,
(x +5) -2(4x-1)=0
Distributing the number inside the bracket we get,
x + 5 - 8x + 2 =0
Simplifying the like terms,
-7x + 7 = 0
Subtract 7 on both sides,
-7x = -7
Divide by -7 on both sides we get,
x = 1
Hence,
The solution of the expression is x = 1.

Susan uses a credit card with an APR of 22.2%. What is the monthly percentage rate on the card?
Answer:
1.85 %
Explanation:
APR refers to the "Annual Percentage Rate." This refers to the rate that is being charged to the borrower on a yearly basis.
It is very easy to get the monthly percentage rate once you know the APR. All you have to do is to divide the APR by the total number of months.
In the situation above, we just have to divide the APR of 22.2% by 12 (number of months on one year).
22.2% ÷ 12 months = 1.85 % per month (this is the monthly percentage rate on the card. Thus, this is the answer.How do you graph Y is less than 3/4 X +2

Mrs. Lin is sewing costumes for her grandchildren. She is making 3 lion costumes, 1 zebra costume, and 2 bear costumes. Fabric costs $7.49 per yard. How much fabric does Mrs. Lin need?
Answer:
rtetrt343444
Step-by-step explanation:
rewrew
Mrs. Lin needs a total of [tex]6 \frac{13}{24} \text{ yards}[/tex] yards of fabric for all the costumes.
To find out how much fabric Mrs. Lin needs for all the costumes, we need to calculate the total yardage required for each type of costume and then sum them up.
Given:
- Bear costume requires 2 1/4 yards.
- Lion costume requires 1 2/3 yards.
- Zebra costume requires 2 5/8 yards.
Let's calculate the total yardage required for each type of costume:
1. Bear costume:
[tex]\[ \text{Yardage for bear} = 2 \frac{1}{4} \text{ yards} \][/tex]
2. Lion costume:
[tex]\[ \text{Yardage for lion} = 1 \frac{2}{3} \text{ yards} \][/tex]
3. Zebra costume:
[tex]\[ \text{Yardage for zebra} = 2 \frac{5}{8} \text{ yards} \][/tex]
Now, let's convert all these mixed numbers into improper fractions:
1. Bear costume:
[tex]\[ \text{Yardage for bear} = 2 + \frac{1}{4} = \frac{8}{4} + \frac{1}{4} = \frac{9}{4} \text{ yards} \][/tex]
2. Lion costume:
[tex]\[ \text{Yardage for lion} = 1 + \frac{2}{3} = \frac{3}{3} + \frac{2}{3} = \frac{5}{3} \text{ yards} \][/tex]
3. Zebra costume:
[tex]\[ \text{Yardage for zebra} = 2 + \frac{5}{8} = \frac{16}{8} + \frac{5}{8} = \frac{21}{8} \text{ yards} \][/tex]
Now, let's sum up the yardages for all the costumes:
[tex]\[ \text{Total yardage} = \text{Yardage for bear} + \text{Yardage for lion} + \text{Yardage for zebra} \][/tex]
[tex]\[ \text{Total yardage} = \frac{9}{4} + \frac{5}{3} + \frac{21}{8} \text{ yards} \][/tex]
To add these fractions, we need to find a common denominator, which is 24:
[tex]\[ \text{Total yardage} = \frac{9 \times 6}{4 \times 6} + \frac{5 \times 8}{3 \times 8} + \frac{21 \times 3}{8 \times 3} \][/tex]
[tex]\[ \text{Total yardage} = \frac{54}{24} + \frac{40}{24} + \frac{63}{24} \][/tex]
Now, let's add the fractions:
[tex]\[ \text{Total yardage} = \frac{54 + 40 + 63}{24} \][/tex]
[tex]\[ \text{Total yardage} = \frac{157}{24} \][/tex]
Now, let's convert the improper fraction to a mixed number:
[tex]\[ \text{Total yardage} = 6 \frac{13}{24} \text{ yards} \][/tex]
So, Mrs. Lin needs a total of [tex]6 \frac{13}{24} \text{ yards}[/tex] yards of fabric for all the costumes.
complete question given below:
Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes. Fabric costs $7.49 per yard. How much fabric does Mrs. Lin need?
Bear= 2 1/4 yards
Lion= 1 2/3 yards
