A pair of shoes sell for $75 from the manufacturing company. If the store sells the shoes for $150 dollars what is the mark-up (percent increase) of the price of the shoe from the manufacturing company to the store?
Help
The mark-up (percent increase) of the price of the shoe from the manufacturing company to the store is 100%.
Given the following data:
Cost price = $75 Selling price = $150To determine the mark-up (percent increase) of the price of the shoe from the manufacturing company to the store:
First of all, we would determine the increase in price of this shoe:
\(Increase = selling\;price -cost\;price\\\\Increase = 150-75\)
Increase = $75
For mark-up (percent increase):
\(Mark\;up = \frac{Increase}{Cost\;price} \times 100\\\\Mark\;up = \frac{75}{75} \times 100\)
Mark-up = 100%

Ifx=3andy=7, evaluate the following expression:3(3y−4x)
When x = 3 and y = 7, the expression 3(3y - 4x) evaluates to 27.
to evaluate the expression 3(3y - 4x) when x = 3 and y = 7, we substitute the given values into the expression and perform the calculations.
plugging in x = 3 and y = 7, we have:
3(3y - 4x) = 3(3(7) - 4(3))
next, we simplify the expression within the parentheses:
3(3(7) - 4(3)) = 3(21 - 12)
further simplifying the expression within the parentheses:
3(21 - 12) = 3(9)
now, we can perform the final calculation:
3(9) = 27

Mr stoves is investing $1500 on a bank account that would give him 3. 7% compounded monthly. What would be his final balance after 10 years?
Mr stove's final balance after 10 years if he invested 1500 on a bank account that would give him 3. 7% compounded monthly is $2,170.37
What would be his final balance after 10 years?A = P(1 + r/n)^nt
Where
P = $1500
r = 3.7% = 0.037
n = monthly = 12
t = 10 years
So,
A = P(1 + r/n)^nt
A = 1,500.00(1 + 0.037/12)^(12×10)
A = 1,500.00(1 + 0.0030833333333333)¹²⁰
A = $2,170.37
Ultimately, Mr stove will have $2,170.37 as his balance after 10 years.

What is the current MARR? The current MARR is percent. (Round the final answer to two decimal places as needed. Round all intermediate values to six decimal places as needed.) c. Should they invest? A. No, they should not invest, as the irrigation system is an extraneous purchase. B. No, they should not invest, as the current rate of return exceeds the MARR. C. No, they should not invest, as the project's first cost is too high. D. Yes, they should invest, as the current rate of return exceeds the MARR.
a. the current IRR on this project is approximately 7.49%.
b. The current MARR (Minimum Acceptable Rate of Return) is not given in the question. Please provide the MARR value so that we can calculate it.
c. The answer to whether they should invest or not depends on the comparison between the IRR and the MARR. Once the MARR value is provided, we can compare it with the calculated IRR to determine if they should invest.
a. The current IRR (Internal Rate of Return) on this project can be found by using linear interpolation with x₁ = 7% and x₂ = 8%. Let's calculate it:
We have the following cash flows: Year 0: -150,000 Year 1: 60,000 Year 2: 75,000 Year 3: 90,000 Year 4: 105,000
Using x₁ = 7%: NPV₁ = -150,000 + 60,000/(1+0.07) + 75,000/(1+0.07)² + 90,000/(1+0.07)³ + 105,000/(1+0.07)⁴ ≈ 2,460.03
Using x₂ = 8%: NPV₂ = -150,000 + 60,000/(1+0.08) + 75,000/(1+0.08)² + 90,000/(1+0.08)³ + 105,000/(1+0.08)⁴ ≈ -8,423.86
Now we can use linear interpolation to find the IRR:
IRR = x₁ + ((x₂ - x₁) * NPV₁) / (NPV₁ - NPV₂) = 7% + ((8% - 7%) * 2,460.03) / (2,460.03 - (-8,423.86)) ≈ 7.49%
Therefore, the current IRR on this project is approximately 7.49%.
b. The current MARR (Minimum Acceptable Rate of Return) is not given in the question. Please provide the MARR value so that we can calculate it.
c. The answer to whether they should invest or not depends on the comparison between the IRR and the MARR. Once the MARR value is provided, we can compare it with the calculated IRR to determine if they should invest.

Two factocy plants are making TV panels. Yesterday, Plant A produced 16,000 paneis: Ten percent of the paneis from Plant A and 3% of the paneis from Plant B were defective. How many panels did Plant B produce, if the overall percentage of defective panels from the two plants was 7% ?
Plant B produced 28,000 panels. Plant B produced 28,000 panels.
Let's assume that Plant B produced x number of panels. Since 10% of the panels from Plant A were defective, then 90% of the panels were good.
Hence, the number of good panels produced by Plant A is 90% of 16,000 = 0.9 × 16,000 = 14,400 panels. Similarly, 97% of the panels produced by Plant B were good, since 3% of them were defective. Hence, the number of good panels produced by Plant B is 97% of the number of panels produced, or 0.97x.
Therefore, the total number of good panels produced from both plants is:14,400 + 0.97xThe total number of defective panels from both plants is 7% of the total number of panels produced.
Therefore:0.07 (16,000 + x) = 1,120 + 0.03x Simplifying the equation, we get:1,120 + 0.03x = 0.07 × 16,000 + 0.07x1,120 + 0.03x = 1,120 + 1,120 + 0.04x0.03x - 0.04x = 1,120x = 28,000
Therefore, Plant B produced 28,000 panels. Plant B produced 28,000 panels.

Find the volume of a cone with a height of 9yd and a base radius of 9yd
The volume of the cone that has a height of 9 yards and a base radius of 9 yards will be 763.02 cubic yards.
What is the volume of the cone?Let h be the height of the cone and A be the base area of the cone.
Then the volume of the cone will be
Volume = (1/3) × A × h
The radius of the base circle is 9 yards. Then the area of the base circle is:
So, the radius of the circle = Diameter /2
Diameter = 9 × 2
Diameter = 18
A = (π/4) d²
A = (3.14 / 4)(18)²
A = 0.785 x 324
A = 254.34 square yards
The height of the cone is 9 yards. Then the volume of the cone is given as,
V = (1/3) x 254.34 x 9
V = 763.02 cubic yards
The volume of the cone that has a height of 9 yards and a base radius of 9 yards will be 763.02 cubic yards.

At the end of 1st Quarter of 2009 the median price of a single-family home in Charleston/No. Charleston was $184,990. Single-family home prices in Charleston/No. Charleston decreased from the 1st Qtr of 2008 by 8.15%. NOTE: Depreciation means a negative value for r. (a). Estimate the median price of a single-family home in the 1st Qtr of 2008.
(b). If the median price of a single-family home falls at the same rate for the next 2 years, estimate the median price of a single-family home in the 1st Qtr of 2011.
The estimated median price of a single-family home in Charleston/No. Charleston in the 1st Quarter of 2008 is $201,048. If the median price continues to decrease at the same rate for the next two years, the estimated median price of a single-family home in the 1st Quarter of 2011 would be $144,458.
(a) To estimate the median price of a single-family home in the 1st Quarter of 2008, we need to calculate the original price before the 8.15% decrease. Let's assume the original price was P. The price after the decrease can be calculated as P - 8.15% of P, which translates to P - (0.0815 * P) = P(1 - 0.0815). Given that the end of 1st Quarter of 2009 median price was $184,990, we can set up the equation as $184,990 = P(1 - 0.0815) and solve for P. This gives us P ≈ $201,048 as the estimated median price of a single-family home in the 1st Quarter of 2008.
(b) If the median price of a single-family home falls at the same rate for the next two years, we can calculate the price for the 1st Quarter of 2011 using the estimated median price from the 1st Quarter of 2009. Starting with the median price of $184,990, we need to apply an 8.15% decrease for two consecutive years. After the first year, the price would be $184,990 - (0.0815 * $184,990) = $169,805.95. Applying the same percentage decrease for the second year, the price would be $169,805.95 - (0.0815 * $169,805.95) = $156,012.32. Therefore, the estimated median price of a single-family home in the 1st Quarter of 2011 would be approximately $144,458.
