## Geometric Approach to Linear Programming Homework

Homework 19, Section 5-3: Applications 31, 33, 34, 36 and

Add a part (D) to application 31: Discuss the effect on the production
schedule and the maximum profit if the profit on a slalom ski remains at $30
but the profit on a trick ski increases to $45.

The wording of number 36 was poorly chosen. The author's intent was to
say that the van can now carry only 7 students (plus, by implication, one
chaperone). Unfortunately, the problem states that the van can only carry 7
people which would imply it can carry only 6 students plus a chaperone. Work
this problem as the author intended by assuming that each van can transport
7 students (plus the needed chaperone).
