** Name __Period___ __IB Grade__ __Points___ ** ** Chapter 6 Project Description & Questions ** The Chapter 6 Project will help you discover how inequalities are used in real-life – specifically in Phone Plans. On the attached sheet you will find a current list of phone plans (as of December 2010), including text prices. On the back of the plans you will find the rubric that will be used to grade this assignment. Using the information sheet, **thoroughly** answer the following questions.

** VERIZON and AT&T Phone Plans: ** 1. If you talk less than 450 minutes how much will you have to pay?

2. If you talk 470 minutes, which plan is cheaper? 450 minutes, 900 minutes, or unlimited plan. Explain your answer.

3. If you talk 525 minutes, which plan is cheaper? 450 minutes, 900 minutes, or unlimited plan. Explain your answer.

4. For what range of minutes is the 450 minute plan the best value? Explain your answer.

5. For what range of minutes is the 900 minute plan the best value? Explain your answer.

6. For what range of minutes is the Unlimited plan the best value? Explain your answer.

** Verizon & AT&T Text Plans: ** 7. Verizon: For what range of texts is the 250 text plan the best? Explain your answer.

8. Verizon: For what range of texts is the 500 text plan the best? Explain your answer.

9. Verizon: For what range of texts is the 5000 text plan the best? Explain your answer.

10. AT&T: For what range of texts is the 200 text plan the best? Explain your answer.

11. AT&T: For what range of texts is the 1500 text plan the best? Explain your answer.

12. AT&T: For what range of texts is the Unlimited text plan the best? Explain your answer.

** Who is the Cheapest? ** For the following scenarios find how much you would pay for each company, with the given plan, and then explain which company is the cheapest.

13. Monthly Total: 455 minutes & 3000 Texts a. T-Mobile (500 minutes, Unlimited Texts) b. Sprint (450 minutes, Unlimited Texts)
