If Julie bought 8 T-shirts, she would be short $28. If she bought 4 T-shirts and 3 baseball hats, she would have $17 left. If each hat cost $5, how much money did she have in the beginning

  • math -

    if she has x dollars,

    8t = x+28
    4t+3h = x-17
    h=5

    so,

    4t+15 = x-17
    x = 4t+32

    8t = 4t+32+28
    4t = 60
    t = 15

    x = 60+32 = 92

    check:

    8*15 = 120 = 92+28
    4*15+3*5 = 75 = 92-17
