Scenarios

The following scenario and questions are designed to draw together the content of the chapter and exercise your understanding of the concepts. There is not necessarily a right answer. The thought process and practice in manipulating the concepts is the goal of this section. The answers to the scenario questions are found at the end of this chapter.

Scenario 21-1
