when estimating a job to bid, a contractors estimator first determines the actual cost of labor using the function l(h)=28.75h, 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? m(b(h)) = 73.19025h m(b(h)) = 31.96h

Answer

Explanation:

Step1: Substitute $L(h)$ into $B(L)$

First, we know $L(h)=28.75h$ and $B(L) = 1.78L$. Substitute $L = L(h)$ into $B(L)$: $B(L(h))=1.78\times(28.75h)=51.175h$

Step2: Substitute $B(L(h))$ into $M(B)$

We know $M(B)=1.43B$. Substitute $B = B(L(h))$ into $M(B)$: $M(B(L(h)))=1.43\times51.175h = 73.18025h$

Answer:

$M(B(h)) = 73.18025h$
