Due March 4, 1999

1. Please get an early start on these problems! Do not put them off to the last minute. Ask for help before the assignment is due. I have office hours before and after class in Science 130. I can also set up special meeting times on Wednesdays. I can also be reached by email.

2. Please read Units 4A, 4B, and 4C of the text. We will spend considerable time working with percentages. It is an important topic!

3. Please do the following problems from the text. There are a lot of problems, but most of them are short. You must show more than the final answer. In all problems, show your work and the use of units clearly.

· Unit 4B: 2c, 5c, 6b, 10d, 12a, 16ad, 22, 31d, 32e.


· Unit 4C: Please take time to practice with scientific notation if you need it (Problems 1 15). Then do problems 18d, 20c, 29, 35.

Just For Fun

Jill and Jack ran a 100 meter race. When Jill crossed the finish line Jack had run only 95 meters. They decided to race again and Jill handicapped herself by starting 5 meters behing the starting line. If they both run at the same constant speed as they did in the first race, who wins the second race? (The solution requies no calculation.)
