Use Table 6.1 for the procedure.
Problems 3, 4, 8, 10, 11, 14, and 17:
Use Example 2 if you are changing from percent form
Problems 5, 6, 9, 12, 15, 16, and 20:

See Examples 5 and 6 for estimation techniques.
Problem 22a : Think of 50% as 1/2.
Problem 22b : Think of 25% as 1/4.
Problem 23 : Think of 10% as 1/10.
Problem 24b : Think of 33 1/3 % as 1/3.
These problems provide practice with the percent problem.
First, identify the percent.
Next, identify the whole quantity.
Finally, identify the remain number and write the proportion.
Take some time to study Example 7 because it illustrates
different types of wording for the percent problem.
These problems are applied examples of the percent problem.
Take a look at Examples 8-13 for practice with these types
of 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.
There are many sources for homework help on the internet.
