Answer:
The cost of one pair of socks is $8.
Step-by-step explanation:
We are given the following in the question:
Cost of leather jacket = $39
Let x be the cost of a pair of socks.
Number of pair of socks purchased = 3
Total cost = $63
We can write the equation for total cost as
[tex]C(x) = 39 + 3x[/tex]
Equating we get,
[tex]C(x) = 63= 39 + 3x\\63 = 39 + 3x\\24 = 3x\\x = 8[/tex]
Thus, the cost of one pair of socks is $8.
