2 CarpetPlus sells and installs floor covering for commercial buildings. Brad Sweeney. CarpetPlus account executive, was just awarded the contract for five jobs.

The following table shows the costs (in hundreds of dollars) for each crew to complete each of the five jobs: Jeb 2 Red White Blue 38 45 37 37 47 32 40 38 34 Crew Green Bronn Use the Hungarian method to solve the problem
