3. You have the following tableau from a maximization problem: 82 RHS 213 81 0 1 13 0 3 82 0 0 22 0 -2 0 -0.5 13 0 0 1 0 S1 0 1 0 0 0 0 0 1 16 2 4 2 (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 :| > 10,000 If the problem is optimal and has multiple optimal solutions, then report infinitely many of them
