Question: For the linear programming model formulated in problem 8 and solved in

a) Determine the sensitivity ranges for the objective function coefficients either manually using the graphical solution or using QM for Windows. i.e.: I want you to return the minimum and maximum coefficients (profit margins) for products A and B for which the original optimum solution still applies.

b) Using manual methods we covered in class, or QM for Windows, determine the shadow prices for additional hours of product time on line 1 and line 2. (Disregard the last sentence of problem 10c.)
