Answer:
Find out the how much does each pair of socks cost when bought individually .
To prove
Let us assume that the original price of one pair of shoes be x.
Than cost for three pair of shoes be 3x.
As given
Maritza is buying a multipack of 3 pairs is socks for $25.98.
She will save $6.39 by buying multipack instead of buying 3 individual pairs of the same socks.
Than the equation becomes
3x - 25.98 = 6.39
3x = 25.98 + 6.39
3x = 32.37
x = $10.79
Therefore each pair of socks cost when bought individually is $10.79 .
