Ashley runs a hardware store. She has decided to apply a markdown of 15% to one item in order to draw customers into the store, and she will apply a markup of 10% to three different items, which she hopes the customers will purchase after purchasing the marked-down item. She has chosen four candidates for this process: a power drill with an initial price of $51.49, a ceiling fan with an initial price of $64.79, a miniature circular saw with an initial price of $45.99, and a screwdriver set with an initial price of $37.39. After applying the changes, the total cost of purchasing one of each item is $3.77 more than it was before applying the changes. Which item was marked down?
a.
power drill
b.
ceiling fan
c.
circular saw
d.
screwdriver set
Answer:
correct answer is option b.
Step-by-step explanation:
so Ashley has markdown one item by 15%
and mark up other items by 10% to get $3.77
assuming she marked ceiling fan mark down by 15%
if each item is sold
= 0.85 × $64.79 +1.1 × $51.49 +1.1 × $45.99 + 1.1 × $37.39
= $203.4285
profit
= $203.4285 - $64.79 -$51.49 - $45.99 -$37.39
=$3.7685 ≅$3.77
hence ceiling fan price will be draw down by 15%
hence correct answer is option b.
The item that was marked down was the b. ceiling fan, from $64.79 to $55.07.
What are markdown and markup?A markdown reduces the cost or price of an item by the percentage markdown.
A markup, on the other hand, increases the cost of the item.
Data and Calculations:Markdown = 15%
Markup = 10%
Items Prices
Power drill $51.49
Ceiling fan 64.79
Circular saw 45.99
Screwdriver set 37.39
Total price $199.66
Increase in the price = $3.77
New price = $203.43 ($199.66 + $3.77)
Decision:Most likely, Ashley will mark down the Ceiling fan to attract customers to purchase other items.
Therefore, the new prices after applying the changes will be:
Items Prices Markup/down
Power drill $51.49 $56.64 ($51.49 x 1.1)
Ceiling fan 64.79 55.07 ($64.79 x 0.85)
Circular saw 45.99 50.59 ($45.99 x 1.1)
Screwdriver set 37.39 41.13 ($37.39 x 1.1)
Total price $199.66 $203.43
Comparison of new total price with old total price:New total price = $203.43
Old total price = $199.66
Increase in cost = $3.77 ($203.43 - $199.66)
Thus, the item that was marked down was the b. ceiling fan.

Hall is baking cookies. The diameter of each cookie is 6 centimeters.
What is the area of each cookie (use 3.14 for pi and round to nearest
tenth)?
Area of each cookie is approximately 28.3 cm2.
The area of a circle can be calculated using the formula A = πr2. Given that the diameter of each cookie is 6 centimeters, the radius would be half of the diameter, which is 3 centimeters. Plugging in the values, we get: A = 3.14 x (3 cm)2 = 3.14 x 9 = 28.26 cm2. Rounded to the nearest tenth, the area of each cookie is approximately 28.3 cm2.
Patty has a parallelogram that has a base of 3 feet and a height of 5 feet. The base and height will each be doubled. Will the area also be doubled? Explain how you know.
Answer:
No, the area will not be doubled. Instead, it will be quadrupled
Step-by-step explanation:
Let the length of the base be b and the height be h.
Original area = b x h
= 3 x 5
= 15 square feet
New area = b x h
= (2 x 3) x (2 x 5)
= 6 x 10
= 60 square feet
Therefore, the area is quadrupled when both the base and the height are doubled.
Answer:
Sample response: No, the area will be multiplied by 4. The original area is 3 × 5 = 15 square feet. If the base and the height are both doubled, then the new area will be 6 × 10 = 60. 60 is 4 times 15.

Tomas Gomez's gross weekly pay is $750. What amount is deducted weekly for Social Security taxes, if the tax rate is 6.2%?
$41.85
$962.55
$52.70
$46.50
Final answer:
The amount deducted weekly for Social Security taxes from Tomas Gomez's gross weekly pay of $750 at a tax rate of 6.2% is $46.50.
Explanation:
The question relates to calculating deductions for Social Security taxes from Tomas Gomez's weekly pay. To calculate the amount deducted weekly for Social Security taxes at a tax rate of 6.2%, you multiply the gross weekly pay by the tax rate.
Gross Weekly Pay: $750
Social Security Tax Rate: 6.2%
Calculation: $750 * 6.2% = $750 * 0.062 = $46.50
Thus, the amount deducted weekly for Social Security taxes from Tomas Gomez's gross pay is $46.50.
find the vertex and the y-intercept of the graph of y = -x^2 + 14x - 47
Answer:
(7,2)
y= -47 or (0,-47)
Step-by-step explanation:
You can use a graphing calculator to find the vertex and y intercept
The coordinates of the vertex are - V(7, 2) and the y - intercept will have coordinates - Y(0, - 47).
What is Parabola?A parabola is a curve which forms by joining all the points which are at an equal distance from a fixed point (the focus) and a fixed straight line (the directrix).The previous section shows that any parabola with the origin as vertex and the y axis as axis of symmetry can be considered as the graph of a function - f(x) = ax² with a ≠ 0.Given is the following equation -
- x² + 14x - 47
We can write the vertex as -
[tex]{\displaystyle V=\left(-{\frac {b}{2a}},{\frac {4ac-b^{2}}{4a}}\right)}[/tex]
So, we can write -
V = (-14/-2, {4 x -1 x -47 - 196}/{-4})
V = (7, 2)
and the point of the parabola intersecting the y - axis has coordinates -
(0, c)
(0, - 47)
Therefore, the coordinates of the vertex are - V(7, 2) and the y - intercept will have coordinates - Y(0, - 47).

???add up the sides?????
Answer:
PR = 20
Step-by-step explanation:
The perimeter is the sum of the 3 sides, thus
4z + z + 3 + 3z + 2 = 45 ← simplify left side
8z + 5 = 45 ( subtract 5 from both sides )
8z = 40 ( divide both sides by 8 )
z = 5
PR = 4z = 4 × 5 = 20
Answer:
40
Step-by-step explanation:
Using the triangle perimeter formula [P=2(l) + 2(w) / 2]:
45 = 2 (z + 3) + 2 (3z + 2) / 2
45 = 2z + 6 + 6z + 4 / 2
45 = 8z + 10 / 2
45 = 4z + 5

David borrowed $2500 from his local bank. The yearly interest rate is 8%. If David pays the full principle and interest in the first year of the loan, how much money will he pay to the bank?
Answer:$2700
Step-by-step explanation: Really depends on the kind of interest, but you would take the initial amount, and multiply it by the APR for the amount of interest, then add the interest to the initial amount.
To repay the full principle and interest in the first year of the loan with an interest rate of 8%, David borrowed $2500 from his local bank, would need to pay a total of $2700 to the bank.
Explanation:To answer your question, we first need to calculate the interest David needs to pay. The formula used to calculate the interest on a loan is: Principal sum x Annual interest rate. David's principal sum is $2500 and the annual interest rate is 8%.
Here's the calculation step-by-step:
Convert the interest rate from a percentage to a decimal by dividing it by 100. So, 8% becomes 0.08.Multiply the principal sum by the interest rate: $2500 * 0.08 = $200.The total amount of money he will pay in the first year is the principal sum plus the interest, which is: $2500 + $200 = $2700.So, if David pays the full principle and interest in the first year of the loan, he will pay a total of $2700 to the bank.

Angle A is 5x-15. Angle B is 2x+21. Solve for x then find the measure for Angle B
To find the measure of Angle B, solve the equation 5x - 15 = 2x + 21, which gives x = 12. Then, substitute x back into the expression for Angle B to get 2(12) + 21 = 45°. Thus, Angle B measures 45°.
Solve for x and find the measure of Angle B
To solve for x and find the measure of Angle B, follow these steps:
Set the expressions for Angle A and Angle B equal to each other:Now, substitute x back into the expression for Angle B:
Angle B = 2x + 21
= 2(12) + 21
= 24 + 21
= 45°
Therefore, the measure of Angle B is 45°.
Find the value of x for which line a is parallel to line b
Answer:
20
Step-by-step explanation:
The question tells us that line a is parallel to line b (even if they don't seem to be in the image).
∠8 = ∠4 and ∠5 = ∠1 since line t crosses the parallel lines.
We are given ∠4 = 3x and ∠5 = 6x.
Since we know ∠8 = ∠4 , we can then say
∠8 = 3x and ∠5 = 6x
Since ∠8 and ∠5 are complementary and combined they form a flat angle of 180 degrees, we can say:
3x + 6x = 180
9x = 180
x = 20
At a clothing store Ted bought 4 shirts and 2 ties for a total price of $95. At the same store, Stephen bought 3 shirts and 3 ties for a total pace of $84. Each shirt was the same price and each tie was the same price.
Which system of equations can be used to find s, the cost of each shirt in dollars and t the cost of each tie in dollars.
Linda bought 1 shirt and 2 ties at the same store. Whats the total price in dollars and cents of Lindas purchase.
Answer:
t(ties) = $8,50 and s(shirts) = $19,50
Linda's purchase total price $36,50
Step-by-step explanation:
In mathematics, a system of linear equations is a set of two or more linear equations with more than one unknown that make up a mathematical problem that consists of finding the values of the unknowns that satisfy those operations. the unknowns are usually represented with letters of the alphabet
For this example, we can represent as a system of linear equations as follows:
For Ted
[tex]4s+2t=95[/tex] where s are shirts, t are ties, and 95 the total price of both products in $.
For Stephen
[tex]3s+3t=84[/tex] where s are shirts, t are ties, and 84 the total price of both products in $.
Each shirt and each tie were buying in the same clothing store which means that it has the same price and we can and we can relate both equations with a system of equations as follows:
[tex]\left \{ {{4s+2t=95} \atop {3s+3t=84}} \right.[/tex]
Using the reduction method, which is to clear in one of the equations with any unknown.
In this case the system has two unknowns, the selected one must be replaced by its equivalent value in the other equation.
Let's clear s in the second equation
[tex]3s+3t=84\\3s=84-3t\\s=\frac{84-3t}{3} \\s=28-t[/tex]
Substituting the value of [tex]s=28-t[/tex] in the first equation
[tex]4s+2t=95[/tex] with [tex]s=28-t[/tex]
[tex]4(28-t)+2t=95\\112-4t+2t=95\\-2t=95-112\\t=\frac{-17}{-2}=8.50[/tex]
We got that the price of a tie is t = $8,50
Substituting the value of t in the first equation in order to obtain the value of s
[tex]3s+3t=84\\3s+3(8.50)=84\\3s+25.50=84\\s=\frac{84-25.50}{3} = 19.50[/tex]
We got that the price of a shirt is s = $19,50
Checking if the result satisfies the equations
With t = 8.50 and s = 19.50
[tex]\left \{ {{4s+2t=95} \atop {3s+3t=2}} \right.\\\left \{ {{4(19.50)+2(8.50)=95} \atop {3(19.50)+3(8.50)=84}} \right.\\\left \{ {{78+17=95} \atop {58.50+25.50=84}} \right.[/tex]
Linda bought 1 shirt and 2 ties at the same store. What's the total price in dollars and cents of Linda's purchase?
If a shirt value is s = $19,50 and a tie value is t = $8,50
Then s + 2t = ?
$19,50 + 2($8,50) = $36,50
The system of equations can be used to find s, the cost of each shirt in dollars and t the cost of each tie in dollars is
4s + 2t = 95
4s + 2t = 953s + 3t = 84
Given:
Cost of shirt = s
Cost of tie = t
4s + 2t = 95 (1)
4s + 2t = 95 (1)3s + 3t = 84 (2)
Multiply (1) by 3 and (2) by 2
12s + 6t = 285 (3)
6s + 6t = 168 (4)
subtract (4) from (3)
12s - 6s = 285 - 168
6s = 117
s = 117/6
s = 19.5
substitute s = 19.5 into (1)
4s + 2t = 95 (1)
4(19.5) + 2t = 95
78 + 2t = 95
2t = 95 - 78
2t = 17
t = 17/2
t = 8.5
Therefore, the cost of each shirt is $19.5 and the cost of each tie is $8.5

If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the integers?
Answer:
First Integer = n = 45
Second Integer = n+1 = 45 + 1 = 46
And Third Integer = n+ 2 = 45 +2 = 47
Step-by-step explanation:
Let First integer = n
Second Integer = n+1
Third Integer = n+2
According to the question given (If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third) the equation will be:
138 - n = (n+1) + (n+2)
Solving the equation:
138 - n = n+1+n+2
138 - n = 2n+3
138 - 3 =2n +n
135 = 3n
135/3 = n
=> n= 45
So, First Integer = n = 45
Second Integer = n+1 = 45 + 1 = 46
And Third Integer = n+ 2 = 45 +2 = 47
