When estimating a job to bid, a contractor’s 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)) = 73.18025h
M(B(h)) = 51.175h
M(B(h)) = 31.96h
M(B(h)) = 30.53h

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

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
