c. How much does the objective function coefficient for variable X2 have to increase before it enters the optimal solution at a strictly positive level?

d. Is the optimal solution to this problem degenerate

e. What is the optimal objective function value if the RHS value for the second constraint changes from 240 to 250?

Answer A&B Rate answer here Solution: Problem is Max Z = 130 X1 + 120 X2 + 200 X3 subject to 2 X1 + 2 X2 + X3 s 400 3X1 + 4 X2 + 6 X3 = 240 4X1 + 6 X2 + 5 X3s 320 9 X1 + 12 X2 + 12 X3
