5. Pie graphs show percentages.

8. Let’s practice.  Number your paper to five and use the graphs to answer the following questions.

9. 1. What food has the most sugar? 2.What percentage of sugar does it have?

14. What is the independent variable for the table?

15. Use the graph paper provided to graph this data.

16. Turn your graph paper around and graph this data.
