Explanation:

Last year, sales at a book store increased from $5,000 to $10,000. The amount by which it increased would be 10000 - 5000 = $5000

The percentage by which the sales increased would be

5000/5000 × 100 = 100%

This year, sales decreased to $5,000 from $10,000.The amount by which it decreased would be 5000 - 10000 = - $5000

The percentage by which the sales increased would be

5000/10000 × 100 = 50%
