Question 1167175: A cell phone plan charges a flat monthly fee of $65 for the first 800 minutes, then $0.11 for each additional minute. A teenager's cell phone bill for last month came to $136.50. How many additional minutes did the teenager use?
You can put this solution on YOUR website! The additional minutes cost 136.50-65.00=$71.50
cost/cost/minute=minutes
so 71.50/0.11=650 additional minutes
