Answer:

6

Step-by-step 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
