Formulate, BUT DON'T SOLVE, a mathematical model with linear constraints and a linear objective function that can be used to solve the following problem. Decision variables should be clearly. described in plain English. Three workers need to be assigned to 3 jobs. The table below displays the times (in hours) required by each worker to complete each job. Each worker must be assigned to a job, and each job must be completed. How should workers be assigned to jobs so that the total time worked is minimized? A 2 3 6 1 2 3 job B 6 4 3 5 4 3 worker
