Question

The population of a small rural town in lowa went from 5700 people in 1998 to 7945 in 2005. What is the rate of change in the population for this town?

Answer 1

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 = (N - O)/O*100` where `p` is that percentage or rate of change, `N` is the New Value and `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 = (7945 - 5700)/5700 * 100`

`p = 2245/5700*100`

`p = 224500/5700`

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