Use the graph below to find the optimal solution for the following problem. Maximize Z = 4x + 5y Subject to: 2x + 3y ? 120 4x + 3y ? 140 x + y 2 80 x,y ? 0 80 -60 40 -20 O 20 4x+3y=1400 x+y=80 2x+3y=120 80 X The objective function level curve is missing from this graph. If the optimal solution is implemented, which one of the following statements is true? The optimal solution is unbounded The problem is infeasible. The problem has a unique optimal solution. The problem has alternative optimal solution.
