Lisa purchased a prepaid phone card for $25 . Long distance calls cost 12 cents a minute using this card. Lisa used her card only once to make a long distance call. If the remaining credit on her card is $19.96 , how many minutes did her call last?

Her call lasted 42 minutes.
Find the difference between 25 and 19.96 and divide the difference by 12.
