CONTROLS, INC., PROBLEM

a. Interpret the ranges of optimality for the objective function coefficients.
b. Suppose that the manufacturing cost increases to $11.20 per case for model A. What is the new optimal solution?
c. Suppose that the manufacturing cost increases to $11.20 per case for model A and the manufacturing cost for model B decreases to $5 per unit. Would the optimal solution change? Use the 100 percent rule anddiscuss.
