You can put this solution on YOUR website!
plan A $25.75 plus .75 per min

A=0.75x%2B25.75


plan B $20.99 plus $1.00 per min

B=x%2B20.99


graph%28

The relative order of the costs changes around 30 or 35 minutes.
0.75x%2B29.75=x%2B20.99
29.75-20.99=0.25x
x=35---------minutes for plans to be equal.

Plan B is better until over 35 minutes.
