Question

A student's cell phone plan has a monthly charge of $40 for 600 minutes of use and a $0.25/minute charge for each additional minute. Last month, the student talked on the phone for 790 minutes. Which of the following is the bill for the month?

Answer 1

So you would subtract 600 from 790 and get 190 then multiply 190 by .25 and you get 47.5 or 47 dollars and 50 cents
