Question

Johnny has a computer repair businesss and he needs to make at least $475 a day to remain in business. He charges an initial fee of $100, and $75 for each hour he works. How many hours must he work each day to remain profitable?

Subtract the fee from the total he needs:

Now divide that by the hourly rate:

375 / 75 = 5

He needs to work 5 hours.
