        W = jars of Western Foods Salsa
        M = jars of Mexico City Salsa

leads to the formulation:

The sensitivity report is shown in Figure 8.16.
  a. What is the optimal solution, and what are the optimal production quantities?
  b. Specify the objective coefficient ranges.
  c. What are the shadow prices for each constraint? Interpret each.
  d. Identify each of the right-hand-side ranges.
