4-31 (For reference to answer question 4-33) Consider the following LP problem: Maximize profit = 5X =6Y Subject to 2X+Y= 120 2X+ 3Y = 240 X,Y= 0 A) What is the optimal solution to this problem? Solve it using solver. B) If a technical breakthrough occurred that raised the profit per unit of X to $8, would this affect the optimal solution? C) Instead of an increase in the profit coefficient X to $ 8, suppose that profit was overestimated and should only have been $ 3. Does this change the optimal solution
