Answer:
$24
Explanation:
Given that
Earning per hour is $15
Admission fee is $9
So, The computation of the total cost would be
= Earning per hour + admission fee of the local carnival
= $15 + $9
= $24
We simply added the earning per hour by working as an assistant coach and the admission fee of the local carnival so that the total cost of skipping practice and going to the carnival could come.
