A cell phone plan costs $30.80 per month for 500 minutes of talk time. It costs an additional $0.08 per minute for each minute over 500 minutes. To get e-mail access, it costs 20% of
the price for 500 minutes of talk time. Your bill, which includes e-mail, is the same each month for 5
months. The total cost for all 5 months is $208.80. Write and solve an equation to find the number of
minutes of talk time you use each month.
Let m represent the number of minutes over 500 minutes each month. Which equation represents
the given situation?
