Tina uses a $50 dollar gift certificate to buy pajamas for 17.97, a necklace for 25.49, and 3 pairs of socks that each cost the same amount. tina has to pay $0.33 because the gift certificate does not cover the total cost of all the items. how much does each pair of socks cost?

17.97 + 25.49 + 3x = 50.33      where x = the cost of a pair of socks

3x + 43.46 = 50.33
3x = 50.33 - 43.46 = 6.87

x =  6.87 / 3 =  2.29

each pair of socks cost $2.29
