athletes per year

Answer 1

To find the rate of change in the number of athletes at Cedarburg High between 2019 and 2023, we can use the formula:

\[
\text{Rate of Change} = \frac{\text{Change in athletes}}{\text{Change in years}}
\]

First, we’ll calculate the change in the number of athletes from 2019 to 2023:

- Number of athletes in 2019: 370
- Number of athletes in 2023: 345

Change in athletes:

\[
\text{Change in athletes} = 345 - 370 = -25
\]

Now, we’ll find the change in years:

\[
\text{Change in years} = 2023 - 2019 = 4
\]

Now we can calculate the rate of change:

\[
\text{Rate of Change} = \frac{-25}{4} = -6.25
\]

Thus, the rate of change in the number of athletes at Cedarburg High between 2019 and 2023 is \(-6.25\) athletes per year.
