Question
**Population Data Analysis**

The table below shows data for the population (in hundreds) of a town for four different years. Find the average rate of change from 1990 to 2000.

| Year                            | 1990 | 1992 | 1995 | 2000 |
|---------------------------------|------|------|------|------|
| Population (in hundreds) |   78  |   83  |   88  |   93  |

**Task:**
Calculate the average rate of change in the population over the years.

**Formula to Calculate Average Rate of Change:**
The average rate of change is calculated by taking the difference in population values and dividing by the number of years between the initial and final values.

**Calculation Steps:**
1. Find the total change in population from 1990 to 2000:
   \[
   \Delta Population = 93 - 78 = 15 \text{ hundred people}
   \]
2. Find the total number of years between 1990 and 2000:
   \[
   \Delta Time = 2000 - 1990 = 10 \text{ years}
   \]
3. Calculate the average rate of change:
   \[
   \text{Average rate of change} = \frac{\Delta Population}{\Delta Time} = \frac{15}{10} = 1.5 \text{ hundred people per year}
   \]

**Result:**
The average rate of change in the population is \(1.5\) hundred people per year.
