  1. 7-31 Consider the following LP problem:

Maximize profit=5X+6Y

subject to2X+Y≤120, 2X+3Y≤240X,Y≥0

  1. What is the optimal solution to this problem? Solve it graphically.
  2. If a technical breakthrough occurred that raised the profit per unit of X to $8, would this affect the optimal solution?
  3. 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?
  1. 7-32 Consider the LP formulation given in Problem 7-31. If the second constraint is changed from 2X + 3Y≤2402X + 3Y≤240 to 2X+4Y≤240,2X+4Y≤240, what effect will this have on the optimal solution?
