Ashley purchased a prepaid phone card for $25. Long distance calls cost 14 cents a minute using this card. Ashley used her card only once to make a long distance call. If the remaining on her card is $21.64, how many minutes did her call last
If we add $0.14 until we get $21.64, we would add it 154.572 times. To check this answer and make sure I’m right, do this equation: 0.14 x 154.572, then you would get 21.64.
