Question

Your heavy-duty mechanics earn $30.00 per hour. Your light-duty servicemen earn $10.50 per hour. Assume a customer wants his engine tuned, oiled, and greased. If the job takes 1 1/2 hours of a mechanic's time, 1 1/2 hours of a serviceman's time, and the overhead rate is 100%, what are the total labor plus overhead charges?

Answer 1

the answer to that is 121.50

Answer 2

Total charge
[(30×1.5)+(10.5×1.5)]+100%=60.75
100%=60.27
So total charge is

(30×1.5)+(10.5×1.5)+100%=121.50
