___ games per year

Answer 1

To determine the rate of change in the number of games won by the Westford baseball team between 2018 and 2022, we can use the formula for the rate of change, which is:

\[
\text{Rate of change} = \frac{\text{Change in games won}}{\text{Change in years}}
\]

First, we need to find the change in games won from 2018 to 2022:

- Games won in 2018: 13
- Games won in 2022: 17

Change in games won:
\[
17 - 13 = 4
\]

Next, we find the change in years:

\[
2022 - 2018 = 4 \text{ years}
\]

Now we can calculate the rate of change:
\[
\text{Rate of change} = \frac{4}{4} = 1
\]

Thus, the rate of change between 2018 and 2022 is **1 game per year**.
