Sample Problems are solved using a consistent step-wise approach.
The problem solving approach is identified in the "Strategy" section.
The "Setup" section contains information from the problem and any necessary data or constants.
In the "Solution" section, every step is shown. This section is followed by a "Think About It" box in which students are reminded to think about whether or not their answers are reasonable. They may also contain additional information to help students see the relevance of the problem, reminders of information from previous chapters, or alternative approaches.
