Recall the TJ Inc.'s problem (Chapter 2, Problem 28). Letting
W = jars of Western Foods Salsa
M = jars of Mexico City Salsa
Leads to the formulation:
Max 1W + 1.25M
s.t.
5W + 7M ‰¤ 4480 Whole tomatoes
3W + 1M ‰¤ 2080 Tomato sauce
2W + 2M ‰¤ 1600 Tomato paste
W, M ‰¥ 0
The computer solution is shown in Figure 3.15.
a. What is the optimal solution, and what are the optimal production quantities?
b. Specify the objective function ranges.
c. What are the dual values for each constraint? Interpret each.
d. Identify each of the right-hand-side ranges.
