**Thomas**, Friday, May 30, 2014 at 2:16pm43. A phone company charges 10 cents per minute for the first 3 minutes of a call, and 10-c cents for each minute thereafter.What is the cost, in cents, of a 10-minute phone call?

- math -
**Ms. Sue**, Friday, May 30, 2014 at 2:17pm10 - 3 = 7

This problem doesn't make sense as the charge per minute is the same -- whether it's the first three minutes or the rest of the phone call.
