A painter charges $15.72 per hour, plus an additional amount for the supplies. If he made $143.65 on a job where he worked 4 hours, how much did the supplies cost?(2 points) Responses $90.77 $90.77 $35.91 $35.91 $80.77 $80.77 $62.88
First, find the painter's earnings from the hourly rate by multiplying the number of hours worked by the hourly rate: 4 hours * $15.72/hour = $<<4*15.72=62.88>>62.88
Then subtract that amount from the total earnings to find the cost of the supplies: $143.65 - $62.88 = $<<143.65-62.88=80.77>>80.77. Answer: \boxed{80.77}.
