Question

A group of students organized a car wash to raise money for a local charity. The students charged $5.00 for each car they washed. In 3 hours, they washed 12 cars. At that rate, how much money could they earn from washing cars for eight hours?

Answer 1

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 2

$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!
