ge Carmen purchased a prepaid phone card for $ 15 . Long distance calls cost 8 cents a minute using this card. Carmen used her card only once to make a long distance call. If the remaining credit on her card is $ 11.48 , how many minutes did her call last?

if you take away 15-11.48=3.52 that is how much money you used. Then dived 60/8=7.5. I hope this helps and if I did the math right
