Quizplus · Accepted Answer

To find the percentage change in sales of hardcover books between Year 1 and Year 3, we need to use the formula:

Percentage change = [(Year 3 value – Year 1 value) / Year 1 value] x 100%

The Year 1 value for hardcover books is 15,000, and the Year 3 value is 6,500. Plugging these values into the formula, we get:

Percentage change = [(6,500 – 15,000) / 15,000] x 100% = -56.67%

Therefore, the percentage change in sales of hardcover books between Year 1 and Year 3 is -56.67%, which is closest to answer choice C (-56.9%).
