Question

Liz's Bakery recently spent a total of $200 on new equipment, and their average hourly

operating costs are $10. Their average hourly receipts are $18. The bakery will soon make

back the amount it invested in equipment. What would the total expenses and receipts both

equal?

Answer 1

25 hours

Explanation:

Given that:

New equipment cost = $200

Hourly operating cost = $10

Hourly receipt = $18

Let h = time

$200 + 10h = total expenses after h hours

18h = total receipts after h hours

Time when expenses and receipts be equal :

$200 + 10h = 18h

200 = 18h - 10h

200 = 8h

h = 200 / 8

h = 25

Hence, expenses will equal receipts after 25 hours
