Suppose you are maximizing the objective z. Identify which one of the following statements is
correct, and answer the corresponding question.
1. The current basic feasible solution is optimal. If so, what is an optimal solution and the
optimal objective value?
5000 or
2. The linear program is unbounded. If so, provide a solution with objective value z =
larger.
3. At least one more iteration of the simplex algorithm is required to solve this problem. If so,
identify which variable will leave the basis (go from being basic to being nonbasic), and which
variable will enter the basis in the next iteration.
