nly once to make a long distance call. if the remaining credit on her card is $20.16 , how many minutes did her call last
2 answers:
It would be 29 minutes on the dot
30 ( total card) - 20.16 (remaining credit)
30 - 20.16 = 9.84
9.84 divided by .24 (cents a minute)
9.84 / .24 =
41
Jenny's call lasted 41 minutes.
