mari went to the mall and spent $47. He bought one shirt for $26 and he bought 3 pairs of socks. Each pair of socks cost the same amount of money.PART AWrite an equation that can be used to find the cost of each pair of socks. Use x to represent the cost of each pair of socks.
Since Mari bought 3 pairs of socks, the equation can be represented as:
3x = 47 - 26
Simplifying the equation, we have:
3x = 21
