Jim pays $75 per month for a cell phone plan plus $0.30 per minute beyond the first 1,000 minutes his bill was $105.60 last month how many minutes did he use
You will subtract 105.60 minus the regular cost which is 75$. 105.50-75 = 30.60. Now you now he went over by 30.60$. When you divide 30.60$ by the .30$ (which is the cost of every minute after 1,000) it will give you 102. He used 102 minutes.
