Answer:
a.1080
Explanation:
If the overhead for this project is 50% of the labor and material costs, the cost is 1.5 times the labor and material costs.
Materials cost is fixed at $520, while labor costs are variable at rate of $10. If project requires 20 labor hours, total cost is:
[tex]C = 1.5*(Material+Labor)\\C=1.5*(\$520+20*\$10)\\C=\$1,080[/tex]
The total cost will be $1,080.
