160.00 because if in 3 hours they wash 12 cars they wash 4 cars every how now if you have 4 cars washed every hour you get 20 dollars and hour because 5.00 every car times 4 cars is 20.00 every hour and 20.00 times 8 equals 160.00

Answer:

$160.00

Explanation:

$5 per car

3 hours = 12 cars


(3hrs)/(12 cars) =(8 hrs)/(x cars)


(3x)/(3) =(96)/(3)

x = 32 cars

32 x $5 = $160

Hope this answers your question!
