According to the table, what was the rate of change between 2012 and 2016?
kids per year

Answer 1

To find the rate of change in summer camp attendance between the years 2012 and 2016, we can use the formula for the rate of change:

\[
\text{Rate of Change} = \frac{\text{Change in Attendance}}{\text{Change in Time}}
\]

First, we identify the attendance for the two years:

- Attendance in 2012: 92 kids
- Attendance in 2016: 93 kids

Now, we calculate the change in attendance:

\[
\text{Change in Attendance} = \text{Attendance in 2016} - \text{Attendance in 2012} = 93 - 92 = 1 \text{ kid}
\]

Next, we determine the change in time:

\[
\text{Change in Time} = 2016 - 2012 = 4 \text{ years}
\]

Now we can calculate the rate of change:

\[
\text{Rate of Change} = \frac{1 \text{ kid}}{4 \text{ years}} = 0.25 \text{ kids per year}
\]

Thus, the rate of change in attendance between 2012 and 2016 is **0.25 kids per year**.
