Figure 16 shows the feasible set for the nutrition problem discussed in Example 1 of Section 3.3, along with the purple line of final cost passing through the optimal point. The figure shows that, as long as the slope of the final cost line is between -3 and – 2 3, the optimal solution will still be at the same vertex.
