a. Solve the following linear programming model by using the graphical method: graph the constraints and identify the feasible region then determine the optimal solution (s) (show your work).

Minimize Z = 3x1 + 7x2

Subject to 9x1 + 3x2 ≥ 36

4x1 + 5x2 ≥ 40

x1 – x2 ≤ 0

2x1 ≤ 13

x1, x2 ≥ 0

b. Are any constraints binding? If so, which one (s)?
