Answer:

M(B(h))=78.18025h

Step-by-step explanation:

First we have the following equations:

L(h) = 28.75h         eq. 1

B(L) = 1.78L            eq. 2

M(B) = 1.43B           eq. 3

To find the selling price based on the estimated number of hours, we need to start replacing equation 1 in equation 2 as:

B(L) = 1.78*B  

B(L(h)) = 1.78*(28.75h)

B(L(h)) = B(h) = 51.175h       eq. 4

Finally, if we weplace equation 4 in equation 3, we get:

M(B) = 1.43B

M(B(h)) = 1.43*(51.175h)

M(B(h)) = 73.18025h

So, the composite function that can be used to find the selling price for the labor portion of a bid based on the estimated number of hours is:

M(B(h)) = 73.18025h
