2. Consider the company describe in the previous problem. Suppose that the cost of hiring workers each period is S100 for each worker until 20 workers are hired, $400 for each worker when between 21 and 50 workers are hired, and $700 for each worker hired beyond 50. Write down the complete linear programming formulation of the revised problem. Solve the revised problem for the optimal solution. What difference does the new hiring cost function make in the solution? a. b. 2. Consider the company describe in the previous problem.
