A painter charges $15.67 per hour, plus an additional amount for the supplies. If he made $190.13 on a job where he worked 7 hours, how much did the supplies cost?

Question

A.
$27.16
B.
$80.44
C.
$90.44
D.
$109.69

Answer 1

To determine the cost of supplies, we first need to calculate how much the painter earned from his hourly rate.

Hourly rate: $15.67/hour
Hours worked: 7
Hourly earnings: $15.67/hour * 7 hours = $109.69

Total earnings from the job: $190.13
Total earnings = Earnings from hourly rate + cost of supplies
Cost of supplies = Total earnings - Earnings from hourly rate
Cost of supplies = $190.13 - $109.69 = $80.44

Therefore, the supplies cost $80.44. Option B.
