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

x = $2.32

Therefore the each pair of socks cost  $2.32 .

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2
