Answer: $8.99

============================================

Work Shown:

x = price of one jump rope before the discount

x-1.80 = price of one jump rope after discount

2*(x-1.80) = total amount Gavin spends

2*(x - 1.80) = 14.38

x - 1.80 = 14.38/2 .... divide both sides by 2

x - 1.80 = 7.19

x = 7.19 + 1.80 ..... adding 1.80 to both sides

x = 8.99

Before the sale, one jump rope costs 8.99 dollars

After the sale, one jump rope costs 8.99 - 1.80 = 7.19 dollars.

This doubles to 2*7.19 = 14.38 dollars which is what Gavin spent in total. This helps confirm the answer.
