games per year

Answer 1

To find the rate of change in games won by Kenny's soccer team between 2020 and 2022, you can use the formula:

\[
\text{Rate of Change} = \frac{\text{Change in Games Won}}{\text{Change in Years}}
\]

1. First, find the number of games won in 2020 and 2022:
- Games won in 2020: 10
- Games won in 2022: 12

2. Calculate the change in the number of games won:
\[
\text{Change in Games Won} = \text{Games in 2022} - \text{Games in 2020} = 12 - 10 = 2
\]

3. Determine the change in years:
\[
\text{Change in Years} = 2022 - 2020 = 2
\]

4. Now, calculate the rate of change:
\[
\text{Rate of Change} = \frac{2 \text{ games}}{2 \text{ years}} = 1 \text{ game per year}
\]

Thus, the rate of change between 2020 and 2022 was **1 game per year**.
