got a little copy/paste problem there.
Christine purchased a prepaid phone card for
$30
. Long distance calls cost
12
cents a minute using this card. Christine used her card only once to make a long distance call. If the remaining credit on her card is
$26.64
, how many minutes did her call last?
To determine how many minutes Christine's call lasted, we need to use the information provided and set up an equation.
Let's denote the cost of the prepaid card with x and the remaining credit after the call with y. It is given that the long distance calls cost n cents per minute.
Now, we can set up the equation:
x - (n * minutes) = y
The cost of the prepaid card, x, is not given in the question, so we don't have enough information to solve for the exact value of minutes.
