Answer:
job estimate = $60.1875
Explanation:
1- labor payment:
The hourly rate is $7.5 and the job will take around 2.5 hours. This means that:
labor payment = 7.2 * 2.5 = $18.75
2- Overhead value:
The overhead value is 85%.
This means that:
its cost would be = 85% * labor payment
= 0.85 * 18.75
= $15.9375
3- Retail cost:
We are given that the retail cost is $25.5
4- getting the job estimate:
job estimate = labor payment + overhead cost + retail
job estimate = 18.75 + 15.9375 + 25.5
job estimate = $60.1875
