Two pairs of shoes and four pairs of socks cost $125, and three pairs of shoes and five pairs of socks cost $182. Find the cost of a pair of socks.

  • math -

    b = shoe price
    s = sock price

    2 b + 4 s = 125 times 3
    3 b + 5 s = 182 times 2

    6 b + 12 s = 375
    6 b + 10 s = 364
    ----------------- subtract
    2 s = 11

    s = $5.50
