Consider Faud Shataras following linear programming formulation: Minimize cost = $1X1 + $2X2 Subject to: X1 +

Question:

Consider Faud Shatara’s following linear programming formulation:
Minimize cost = $1X1 + $2X2
Subject to: X1 + 3X2 ≥ 90
8X1 + 2X2 ≥ 160
3X1 + 2X2 ≥ 120
X2 ≥ 70
(a) Graphically illustrate the feasible region to indicate to Faud which corner point produces the optimal solution.
(b) What is the cost of this solution?
