## Homework Statement

A customer is choosing between two cellular phone plans.

One plan has a monthly fee of $50 for an allowance of

500 minutes per month. If the customer uses more than

500 minutes, the charge is $0.35 per additional minute used.

The other plan has a monthly fee of $75 for an allowance of

1000 minutes per month. If the customer uses more than

1000 minutes, the charge is $0.40 per additional minute. After

how many minutes used are the monthly costs of the plans

equal?

## Homework Equations

This is how I set it up...

Plan 1: (<=500 min) x= $50; (>500 min) x= $50 + $0.35m

Plan 2: (<=1000 min) x= $75; (>1000 min) x= $75 + 0.40m

## The Attempt at a Solution

The answer is 4000 minutes, but I don't know how to proceed. Any help is appreciated.
