In class this week we reviewed percentages and how to find them. Your assignment is to complete all of 3.1 (we started in class) and the 3 pages of section 3.2. I had recommended doing column a only, but do check your answers and make sure you can do this. The answer key should help you out. If you are taking a while to get the hang of it, please do all. There will be a quiz on Monday on percents, ratios, and proportions.
I reviewed how to do percents as a proportion in class and I wish the book showed that technique for each of the 3 different kinds of problems you see in section 3.2.
For example, if you have to find 8% of 25 you can simply multiply .08 times 25 or
set up a proportion 8/100 = n/25.
Either way will get you the same answer. Try using the proportion method some of the time to be sure you feel comfortable with it.
