3. Ten jobs are to be completed by three men during the next week. Each man works a 40-hour week. The times for the men to complete the jobs are shown in the table below. The values in the cells assume that each job is completed by a single person; however, jobs can be shared with completion times being determined proportionally. If no entry exists in a particular cell, it means that the corresponding job cannot be performed by the corresponding person. Set up and solve a linear programming model that will determine the optimal assignment of men to jobs. The goal is to minimize the total time required to complete all the jobs.
