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

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

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.

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

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

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 95 100 105 110

Algebraic Solution

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
