athletes per year

Answer 1

To find the rate of change in the number of athletes at Seaside High between the years 2021 and 2025, you can use the formula for the rate of change:

\[
\text{Rate of change} = \frac{\text{Change in number of athletes}}{\text{Change in time}}
\]

1. **Change in number of athletes**:
- Number of athletes in 2021: 589
- Number of athletes in 2025: 596
- Change = 596 - 589 = 7 athletes

2. **Change in time**:
- From 2021 to 2025 is 4 years (2025 - 2021 = 4).

Now we can plug in these values:

\[
\text{Rate of change} = \frac{7 \text{ athletes}}{4 \text{ years}} = 1.75 \text{ athletes per year}
\]

Therefore, the rate of change between 2021 and 2025 is **1.75 athletes per year**.
