Question

Robin baked 702 cookies.He sold them in boxes of 18. After selling all of the boxes of cookies for the same amount each, he earned $136.50.what was the cost of one box of cookies

Answer 1

cost of a box is $3.5

Explanation:

given data

sold box = 18

earned = $136.50

solution

we consider here number of boxes of cookies is x

and

for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is

Tyler sold =
`(702)/(18)`

Tyler sold = 39 boxes

and

now we consider here y as cost of each box of cookies,

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes

so

cost of each box =
`(136.5)/(39)`

cost of each box = 3.5

Thus, the cost of each box was 3.5
