Question

Lisa purchased a prepaid phone card for $30. Long distance calls cost 6 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 $27.84, how many minutes did her call last?

Answer 1

My answer is 27.48 minutes

Step-by-step explanation: what i did to get this answer is i subtracted my numbers and add so i added $30 + 6 ( don't have to put the dollar sign when you add your numbers together) and i got 36 as my answer and then after i did that i subtracted $27.84 - 36 and got 27.48 as my answer.
