Marvin's Bakery recently spent a total of $700 on new equipment, and their average hourly operating costs are $10. Their average hourly receipts are $80. The bakery will soon make back the amount it invested in equipment. How many hours will that take?

10 hours

Step-by-step explanation:

So what you would do is subtract 10 from 80 because you earn $80 and lose $10 out of that $80 every hour and you would end up with $70 and to find how long it would take to earn $700 is you would divide 700 by 70 and your final awnser would be 10 hours.
