"Consider the following LP problem: Maximize profit = 1X1 + 1X2 Subject to 2X1 + 1X2 100 1X1 + 2X2 100 a) What is the optimal solution to this problem? Solve it graphically. b) If a technical breakthrough occurred that raised the profit per unit of X1 to $3, would this affect the optimal solution? c) Instead of an increase in the profit coefficient X1 to $3, suppose the profit was overestimated and should have only been $1.25. Does this change the optimal solution? "
