Question

Jenny purchased a prepaid phone card for $30 . long distance calls cost 6 cents a minute using this card. jenny used her card only once to make a long distance call. if the remaining credit on her card is $27.12 , how many minutes did her call last

Answer 1

So if she still has $27.12, then during her call, she used a total of $2.88.

$2.88 = 288 cents. 

Therefore 288 divided by 6 = 48

Therefore the answer is 48 minutes.
