When estimating a job to bid, a contractor’s estimator first determines the actual cost of labor using the function L(h) = 28.75

h, where h is the number of estimated hours it will take to complete the job. Next, the estimator adds the labor burden, which accounts for taxes and insurance, using the function B(L) = 1.78L. Finally, the estimator calculates the selling price, including the markup for overhead and profit, using the function M(B) = 1.43B. Which composite function can be used to find the selling price for the labor portion of a bid based on the estimated number of hours?

Answer:

M(h) = 73.18025h

Step-by-step explanation:

The composite function is ...

M(B(L(h))) = M(B(28.75h)) = M(1.78(28.75h)) = M(51.175h)

= 1.43(51.175h) = 73.18025h

The composite function is ...

M(h) = M(B(L(h))) = 73.18025h
