A clothing store is having a sale on holiday socks. Each pair of socks costs x dollars. You leave the store with 6 pairs of socks and spend a total of (6x-14) dollars. You pay with $40. How much change do you receive?

Answer: $ 14

Step-by-step explanation:

Since, the cost of 1 pair of socks = x

The cost of 6 pair of socks = 6 x

Total amount spend = $ 40

According to the question,

6 x - 14 = 40

6 x = 40 + 14

6 x = 54

x = 9

Thus, the original price of one pair of socks = $ 9

⇒ The original price of 6 pairs of socks = $ 54

Hence, the total change = original price of socks - the price of socks in the sale = 54 - 40 = $ 14
