Answer:
6
Explanation:
Given that:
Cost of shirt = $12.50
Cost per socks = $2.50
Total amount paid = $27.50
How many pairs of socks was purchased =?
Let Number of socks purchased = x
Total amount paid = cost of shirt + (cost per socks * number of socks)
27.50 = 12.50 + (2.50 * x)
27.50 = 12.50 + 2.50x
27.50 - 12.50 = 2.50x
15 = 2.50x
x = 15 / 2.50
x = 6
Number of pairs purchased = 6
