Look over the lessons in Chapter 7. Why do you think the editors of this textbook put all of this material together in one chapter? What connects all of the lessons? Are there any lessons in Chapter 7 that do not fit in the chapter? Where should they go instead? Also, do you think other lessons could be added to this chapter? If so, which ones, and why? If not, why not?
(Yes, there are many questions to answer here. You will be graded on your ability to produce well-reasoned answers.)

MIXTURES are too much WORK!
The sections on Mixtures and Work simply add one or two steps from your previous knowledge from Chapters 3 and 4. Answer the following questions to help you address your issues with these types of problems.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
