If no optimal solution exists, indicate whether the feasible region is empty or the objective function is unbounded, HINT [See Example 1.] (Enter EMPTY if the region is empty. Enter UNBOUNDED if the function is unbounded.) Minimize c = x + y subject to x + 7y28 7x + y28 x 20, y 20. ( x, y ) = Need Help? Read It
