Question: 4. Repeat problem (a) and (b) from problem 3 using the following tableau from a minimiza- tion problem: z S1 21 0 13 0 22

4. Repeat problem (a) and (b) from problem 3

4. Repeat problem (a) and (b) from problem 3 using the following tableau from a minimiza- tion problem: z S1 21 0 13 0 22 3 -2 S2 -2 Z 1 0 RHS 12 4 8 I 1 1 0 0 1 0 0 1 2 1 23 -0.5 0 (a) Report the feasible solution that this tableau corresponds to and its value. (b) Using Simplex, determine if the previous tableau is optimal explain why or why not. In addition, do the following: If it is not optimal, report a new entering variable and exiting variable and update the tableau. If there is no exiting variable because the LP is unbounded, then report a feasible solution witha large value, specifically [z] > 10,000. If the problem is optimal and has multiple optimal solutions, then report infinitely many of them
