Question 32944: Sorry to bother you, but i have a question. How do I begin my equation. I need to find equations which represent the price of both plans plan A and Plan B. Then find a break even point, and afterwards graph both lines.
I have 2 cellphone companies, one is plan A: 30.00/month, price/minute $0.15
and the other company Plan B is no montly payment/ price/minute $0.20

i will then be able to find out which is the better plan if a person who talk about 750 minutes/month.
Thanks in advance.

PLAN A COSTS 30+(.15*750)=30+112.50 OR 142.50
PLAN B COSTS .20*750 OR 150.00
THEREFORE PLAN A IS CHEAPER FOR 750 MINUTES
