 * Buying a Phone**

Your Name ___________________

Partner’s Name___________________

Each person in your group of two needs to choose one type of pre-paid phone from the myrateplan.com webpage. **You must choose a different phone from your partner.** Each person needs to complete items 1 to 7 on their own, however I want you to work with your partner on questions 8, 9, and 10.


 * Go to the page [|__http://www.myrateplan.com/wireless_prepaid__].
 * On the first page that arises click on the **traditional** plan and then enter **01475** for the zip code. Hit enter.
 * You will now be linked to the page you will need to complete this worksheet.

1. Choose one of the phones listed on the right. Which phone did you choose?(1pt)

2. How much will this phone cost per minute used? (1pt) (if there is a range, choose the highest price. For example for the ToGo phone it says it costs between $.15- $.33, use $.33 for this assignment)

3. Could your rate in answer 2 be considered the constant rate of change? Why or why not? (4pts)

4. What mathematical operation would you need to use to determine how much the phone would cost after 5 minutes? (1pt)

5. Are there any additional fees that will occur before you have used any minutes? (for some plans this is yes, for example the GO phone charges $1 day, for others the answer is no) (1pt)

a. If Yes, what are these fees for and how much are they? (1pt)

b. Could these fees be considered your starting point? Why or why not?(2pts)

6. Using a calculator, complete the table based on how much the phone would cost (y) after (x) amount of minutes using the phone. (4pts)


 * x (minutes) || 0 || 10 || 20 || 30 ||
 * y (price) ||  ||   ||   ||   ||

7. Write an equation in the form y = mx + b. Remember what is the constant rate of change? What is the starting point? (4pts)


 * Work on 8,9, and 10 with your partner. Note you will both have different graphs for No. 8.**

8. Graph the ordered pairs you created in Question 6. (Be sure to label both axes on your graph and clearly identify the scale you use on each axis.)

9. Compare the cost of your phone with the cost of your partners. Which phone do you think is the best to purchase for you? Why? Use at least two complete sentences to explain. (4pts)

10. What advice would you offer to someone who was about to purchase a new pre-paid phone? Use at least two complete sentences in your response. (2pts)
