Answer:
I want to know the sides of a pizza if the width is 9 inches larger than the height and the area is 250 squared inches.
My brother wants to know how long his bed is if it has an area of 2m and the width is .5m larger than the height.
My father wants to know whats the size of a football field if the area is 57,600 square feet given that the length is 200 ft larger than the width.
Explanation:
To solve this you just have to think on the unknown value and represent it as "X" in the first problem we do not know the length or width but we have a values given between them, so if "x" is the height then the width becomes "x+9" so those two values multiplied become the area.

With this you just keep solving the others.
My brother wants to know how long his bed is if it has an area of 2m and the width is .5m larger than the height.
2m as an area and the height is "x"

My father wants to know whats the size of a football field if the area is 57,600 square feet given that the length is 200 ft larger than the width.
57,600 is the area and width will be "x"

Answer:
monthly payment = $669.76
Explanation:
using the present value of an annuity formula we can determine the monthly payment:
monthly payment = present value of an annuity / PV annuity factor
- present value of an annuity = $20,000 - $5,000 = $15,000
- PV annuity factor 2%, 30 periods = 22.396
monthly payment = $15,000 / 22.396 = $669.76
Answer: $108.24 per machine hour
Explanation:
Given that,
If the company incurs 7,200 machine hours then,
Total variable production quality cost = $556,416
Total fixed production quality cost = $226,008
Variable production quality cost per machine hour:
= 
= 
= $77.28 per machine hour
If the company incurs 7,300 machine hours then,
Total production cost = variable production quality cost + fixed production quality cost
= $77.28 per machine hour × 7,300 + $226,008
= $564,144 + $226,008
= $790,152
Total production quality cost per unit =
=
= $108.24 per machine hour
