Use Solver to create a Sensitivity Report for question 15 at the end of Chapter 3, and answer the following questions:
a. Is the solution degenerate?
b. Is the solution unique?
c. Explain the signs of the reduced costs for each of the decision variables. That is,
considering the optimal value of each decision variable, why does the sign of its
associated reduced cost make economic sense?
d. Suppose the cost per pound for Feed 3 increased by $3. Would the optimal solution change? Would the optimal objective function value change?
e. If the company could reduce any of the nutrient requirements, which one should
it choose and why?
f. If the company could increase any of the nutrient requirements, which one
should it choose and why?
