Grace, a hairdresser, charges $18 for a haircut and $70 for a perm. She did 36 perms this month. The total amount of money Grace took in was $4,608. How many haircuts did Grace do this month?
116 haircuts since 36 times 70 is 2520 and that is the amount of money she earned for perms. So then 4608 subtracted by 2520 is 2088 and 2088 divided by 18 is 116 so that is the answer.
