Question

Tina uses 50$ gift certificate to buy a pair of 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 dose not cover the total of all the items. how much does each pair of socks cost?

Answer 1

17.97 + 25.49 + 3x = 50.33
17.97 + 25.49 + 3x - 17.97 - 25.49 = 50.33 - 17.97 - 25.49
3x = 6.87
3x/3 = 6.87/3
x = 2.29 per pair of socks

Answer 2

$50 + 0.33= $50.33; 17.97 + 25.49 + 3s = 50.33; 43.46 + 3s= 50.33;
50.33 - 43.46= 6.87; 3s= 6.87; 6.87 ÷ 3= $2.29
The answer is $2.29.

Hope this helps :)
