To find the cost of each pair of socks, we can set up an equation based on the information provided.
Let \( x \) represent the cost of each pair of socks.
Amari spent $26 on one shirt and \( 3x \) on three pairs of socks. The total amount spent is $47.
We can express this with the following equation:
\[ 26 + 3x = 47 \]
This equation can be used to find the cost of each pair of socks.
