Amy and Kim found a sale in a sporting goods store. Amy spent $33 on 2 pair of shorts and 3 packages of socks. Kim spent $27 on 1 pair of shorts and 5 packages of socks. How much does one of each item cost?

  • math -

    2 shorts + 3 socks = 33
    1 shorts + 5 socks = 27
    so,
    2 shorts + 10 socks = 54

    subtract one equation from the other:

    7 socks = 21
    socks = 3
    so, shorts = 12
