games per year

Answer 1

To calculate the rate of change in the number of games won by Lauren's soccer team between 2014 and 2016, you can use the formula for the rate of change:

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

From the table:

- In 2014, the games won were 21.
- In 2016, the games won were 23.

Now, calculate the change in games won and the change in years:

\[
\text{Change in Games Won} = 23 - 21 = 2
\]
\[
\text{Change in Years} = 2016 - 2014 = 2
\]

Now substitute these values into the rate of change formula:

\[
\text{Rate of Change} = \frac{2 \text{ games}}{2 \text{ years}} = 1 \text{ game per year}
\]

Therefore, the rate of change between 2014 and 2016 is **1 game per year**.
