CarpetPlus sells and installs floor covering for commercial buildings. Brad Sweeney, a

CarpetPlus account executive, was just awarded the contract for five jobs. Brad must now

assign a CarpetPlus installation crew to each of the five jobs. Because the commission

Brad will earn depends on the profit CarpetPlus makes, Brad would like to determine an

assignment that will minimize total installation costs. Currently, five installation crews are

available for assignment. Each crew is identified by a color code, which aids in tracking of

job progress on a large white board. The following table shows the costs $($in hundreds of

dollars$)$ for each crew to complete each of the five jobs:

Client

Project Leader $123$

Jackson $101632$

Ellis $142240$

Smith $222434$

Brown $2634444328$

a$.$ Develop a network representation of the problem.

b$.$ Formulate and solve a linear programming model to determine the minimum cost

assignment.
