**Problems 1-2**

There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid to give your opinion. For the most part, these questions do not have “right” or “wrong” answers. You should spend about five minutes in answering each of these questions.
Problems 3-29

These multiple choice questions require a great deal of thought because most of them give you more information that you need to answer the question. You also need to be careful about units; for example, Problem 13 gives input in gallons of water per minute, but then asks for the number of hours to fill the pool. You must convert minutes to hours to obtain the answer to the asked question.
Problems 30-31

The answers for these, of course vary. It may be the case that you have not worked all of the named problems, in which case you should answer these questions based on your experiences of the problems you have worked in this section.
Problems 32-40

The idea of real problem-solving is that you do NOT have a template or an example to mimic. You need to develop a strategy for solving these problems, with the idea of building your problem-solving skills. Since these are level 2 problem, we will, however, give you first-step hints here:

**Note:** Homework Hints are given only for the Level 1 and Level 2 problems.

However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.

On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.
