Question 3: Graphically solve the following problem.

Minimize the cost = X + 2 Y

Subject to:      X+3Y  >=  90

                        8X + 2Y >= 160

                        3X + 2Y >= 120

                        Y  <=   70

                        X,Y  >=  0  

  1. What is the optimal solution?
  2. Change the right hand side of constraint 2 to 140 (instead of 160) and resolve the problem. What is the new optimal solution?
