Question

A local car wash is open 8 hours each day. It uses 1/3 of a container of wax for each car. The car wash waxes an average of 8 1/2 cars per hour. How many containers of wax does the car wash use in 1 day?

Answer 1

22.67 containers.

Explanation:

The number of cars washed is the average by the total hours worked:

`C_(total)=\bar xt,\bar x=8.5,t=8\\\\C_(total)=8.5* 8=68`

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

`Containers=\bar x_c n,n=68,\bar x_c=(1)/(3)\\\\=(1)/(3)* 68\\\\=22.67`

Hence, the car wash uses 22.67 containers of wax per day.
