4. Repeat problem (a) and (b) from problem 3 using the following tableau from a minimiza- tion problem: 82 RHS 2 210 201 0 0 12 3 -2 -0.5 13 0 0 1 51 0-2 12 1 2 4 0 1 8 (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 1-1 > 10,000. If the problem is optimal and has multiple optimal solutions, then report infinitely many of them
