Answer:
The each pair of socks cost $2.32 .
Step-by-step explanation:
As given
Tina uses $50 gift certificate to buy a pair of PJs for $17.97, a necklace for $25.4, 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 cost if all the items.
Total cost Tina uses for shopping = $50 + $0.33
= $50.33
Let us assume that the cost of one pair of socks be x.
Than the equation becomes
17.97 + 25.4 + 3x = 50.33
3x = 50.33 - 17.97 - 25.4
3x = 50.33 - 43.37
3x = 6.96
[tex]x = \frac{6.96}{3}[/tex]
x = $2.32
Therefore the each pair of socks cost $2.32 .
