A painter charges $15.91 per hour, plus an additional amount for the supplies. If he made $175.81 on a job where he worked 6 hours, how much did the supplies cost?

First, find out how much the painter charged for 6 hours, without adding the amount for supplies. You’d multiply 6 with $15.91, to get $95.46. Then, subtract $95.46 from $175.81, to find the additional amount of supplies.
