Agroup 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? and show how u got the answer step by step

12/3 = 4 4 cars per hour 4 x 5 = $20 20 x 8 = $160 for 8 hrs

First you would divide 12 cars by 3 hours to see how many cars get washed per hour
Then you know that 4 cars get washed in one hour so you multiply it by $5.00 because you want to see how much money they earn in one hour

After you know they earn $20.00 per hour you multiply that by 8 because you want to see how much money they earn in eight hours

So your final answer is $160 for washing cars in 8 hours
