Consider the following model:
Minimize Z = 40x1 + 50x2,
Subject to

and
x1 ‰¥ 0, x2 ‰¥ 0.
(a) Use the graphical method to solve this model.

(b) How does the optimal solution change if the objective function is changed to Z = 40x₁ + 70x₂? (You may find it helpful to use the Graphical Analysis and Sensitivity Analysis procedure in IOR Tutorial.)

(c) How does the optimal solution change if the third functional constraint is changed to 2x₁ + x₂ ≥ 15? (You may find it helpful to use the Graphical Analysis and Sensitivity Analysis procedure in IOR Tutorial.)
