Plan 1- Flat fee of $45 a month

Plan 2- $15 a month plus 45 cents per minute

What two equations would you use to graph the two plans?

After how many minutes does it not make a difference which plan you use?

**drwls**, Saturday, October 27, 2007 at 7:53pmLet Y be the monthly cost in dollars, and t the totl minutes of all calls in one month

Plan 1: Y1 = 45

Plan 2: Y2 = 15 + 0.45 t

That's two equations.

Set Y1 = Y2 to solve for the t that makes the charges equal.
