To find the cost of each pair of socks, we can set up an equation based on the total amount Amari spent.
Let \( x \) represent the cost of each pair of socks. Since Amari bought one shirt for $26 and 3 pairs of socks, we can express the total cost as follows:
\[
26 + 3x = 47
\]
This equation represents the total amount spent ($47), where $26 is the cost of the shirt and \( 3x \) is the total cost of the 3 pairs of socks.
