A group of friends are planning a road trip. If they all contributed $24, then they would be $6 short of the total. If they all contributed $25, then they would have $3 more than needed. What is the total cost of the trip?

    $222

  • arithmetic -

    let the number in the group be x

    24x + 6 = 25x - 3
    -x = -9
    x = 9

    cost = 24(9) + 6 = 222 , just like Ms Sue said.
