Answer:
the house painter earns $ 1,140 for a 70-hour week
Explanation:
Given that a house painter charges $ 12 per hour for the first 40 hours he works, time and a half for the 10 hours after that, and double time for all hours after that, to determine how much does he earn for a 70-hour week The following calculation must be carried out, proposing a linear function:(40 x 12) + (10 x 12 x 1.5) + (20 x 12 x 2) = X40 x 12 + 10 x 18 + 20 x 24 = X480 + 180 + 480 = X1,140 = XTherefore, the house painter earns $ 1,140 for a 70-hour week
