6. Cell Phone Comparison
You and your friend just signed up for pay as you go cell phone plans. You signed up with Verizon, which chagres you an initial fee of $15.00, but only charges 10 cents for each minute you talk. Your friend signs up with Sprint which charges no initial fee, but has a 25 cent per minute charge.

11. Verizon vs. Sprint
How much is each plan going to cost if we talk for 1 hour (60 minutes)?

12. Verizon vs. Sprint
How much is each plan going to cost if we talk for 1 hour (60 minutes)?

13. Write a sentance
If I talk for an hour using the Verizon Plan it will cost me $21.
If I talk for an hour using the Sprint Plan it will cost me $15.

14. Set up Question #4 Table – Go up by 5’s starting at 80
USE THE CALCULATOR
Graph – Use the table to plot your points

15. Now let’s see when the cost the same
Using a table: Let’s use the calculator X Y1 Y2 85
23.5
21.25 90 24
22.5 95
24.5
23.75
100 25
105
25.50
26.25
110 26
26.5

16. Now set up a graph 26 25 24 23 75 80 85 90 95 100 105 110 Sprint
Verizon 26 25 24 23 75 80 85 90 95

17. Algebraic Solution

18. So…Solving Equations with Variables on both sides
Get rid of all the parenthesis and combine like terms on each side
Get all the variables to one side
Get all the whole numbers to the other side
Solve for the variable

22. Three Possible Solutions
If you can solve for a variable there is ONE SOLUTION
If you reach a FALSE statement there is NO SOLUTION

23. Three Possible Solutions
If you can solve for a variable there is ONE SOLUTION
If you reach a FALSE statement there is NO SOLUTION
If you reach a TRUE statement the the solution is _________________________________

24. Three Possible Solutions
If you can solve for a variable there is ONE SOLUTION
If you reach a FALSE statement there is NO SOLUTION
If you reach a TRUE statement the the solution is All Real Numbers

25. Let’s review everything we know
Distribution
Combine like terms
Variables to one side
Numbers to the other
