    Hello
    5 adults and 3 teenagers for one day paid them a total of $224 per hour
    5A + 3T = 8 * 224
    3 adults and 5 teenagers for one day paid them a total of $160 per hour
    3A + 5T = 8 * 160
    Adding both
    => 8A + 8T = 8 * 224 + 8 * 160
    => A + T = 384
    2A – 2T = 8(64)
    => A – T = 256
    2A = 640
    => A = 320
    T = 64
    The hourly rate paid day to each adult is $320
