    Answer: her call lasted for 26 minutes.

    Step-by-step explanation:

    Let x represent the number of minutes that her call lasted.

    Rachel purchases a prepaid phone card for $15. Long distant calls cost $.21 a minute using this card. This means that the total cost of x minutes of long distant calls would be 0.21 × x = 0.21x

    If the remaining credit on your card is $9.54, it means that

    0.21x + 9.54 = 15

    0.21x = 15 – 9.54

    0.21x = 5.46

    x = 5.46/0.21

    x = 26 minutes

    Answer:

    Rachel was on the long distance call for 26 minutes

    Step-by-step explanation:

    First we have to find the total amount that she spent so we subtract, 15-9.54=5.46

    then we divide that by .21 to find the number of minutes that she spent on the call.  5.46/.21=26
