The town had a 39.4% change from 1998 to 2005

Explanation:

The percentage or rate of change between two numbers over time can be calculated using the formula:

$p = \frac{N - O}{O} \cdot 100$ $p = (N - O)/O*100$ where $p$ $p$ is that percentage or rate of change, $N$ $N$ is the New Value and $O$ $O$ is the Old Value. We are given the New Value (7945) and the Old Value (5700) which we can substitute into the formula and solve for $p$ $p$ :

$p = \frac{7945 - 5700}{5700} \cdot 100$ $p = (7945 - 5700)/5700 * 100$

$p = \frac{2245}{5700} \cdot 100$ $p = 2245/5700*100$

$p = \frac{224500}{5700}$ $p = 224500/5700$

$p = 39.4 %$ $p = 39.4%$ rounded to the nearest tenth of a percent.
