Question

Linda purchased a prepaid phone card for $30 . Long distance calls cost 14 cents a minute using this card. Linda used her card only once to make a long distance call. If the remaining credit on her card is $25.94 , how many minutes did her call last?

Answer 1

30 - 25.94 = 4.06

4.06 / 0.14 = 29

Linda's call was 29 minutes long.
