Q 
151. Direct cost for a plumbing job is $2,500.00 for labor and material. The supplementary costs are as follows:
Overhead - 6.5%.
Permits - $150.00.
Overhead Cost on Job - 2%.
Contingency - 3%.
Profit - 10%. 
The permit costs are $75.00 the balance is transferred to the contingency.

B. 2,837.50
C. 2,737.50
D. 2,637.50.
A 
A. 2,937.50.
Overhead cost: 2,500.00x6.5=$162.50
Permits:
150.00-75.00=75.00
Overhead cost: 2,500.00x0.02=50.00
Contingency: 2,500.00x0.03=75.00
Transferred to contingency: 75.00
Direct cost = Labor + Material = 2,500.00
Overall cost of the project:
162.50+75+50+75+75+2,500 = 2,937.5
