The problem asks to calculate the rate of change between the years 2014 and 2017 based on the number of books read at Dover High School.

From the image, the table provides the following data for books read:

- 2014: 673 books
- 2017: 672 books

### Rate of Change Formula:
The rate of change is calculated using the formula:

\[
\text{Rate of Change} = \frac{\text{Change in value}}{\text{Change in time}}
\]

In this case:
- Change in value = \( 672 - 673 = -1 \) (books)
- Change in time = \( 2017 - 2014 = 3 \) (years)

\[
\text{Rate of Change} = \frac{-1}{3} = -0.33
\]

So, the rate of change is approximately \(-0.3\) books per year when rounded to the nearest tenth.

Here are 5 related questions to extend your understanding:
1. How would you calculate the average number of books read between 2013 and 2017?
2. What if the change between two years was an increase—how would that affect the rate of change?
3. Could you graph this data to visualize the trend? What would that graph look like?
4. What other methods could be used to analyze trends in data like this?
5. How could outliers affect the interpretation of this data?

**Tip:** When calculating the rate of change, always make sure to subtract the earlier value from the later one to get the correct sign of the result.

According to the table, what was the rate of change between 2014 and 2017? Round your answer to the nearest tenth.
