Question

leah was in charge of keeping attendance for a local summer camp each year. summer camp attendance according to the table, what was the rate of change between 2012 and 2016? kids per year

Explanation:

Step1: Calculate the change in the number of kids

The formula for the change in the number of kids is $\text{Change in kids}=\text{Final value}-\text{Initial value}$.
Here, the initial value (in 2012) is $166$ and the final value (in 2016) is $280$. So, $\text{Change in kids}=280 - 166=114$.

Step2: Calculate the change in years

The formula for the change in years is $\text{Change in years}=\text{Final year}-\text{Initial year}$.
Here, the initial year is $2012$ and the final year is $2016$. So, $\text{Change in years}=2016 - 2012 = 4$.

Step3: Calculate the rate of change

The formula for the rate of change is $\text{Rate of change}=\frac{\text{Change in kids}}{\text{Change in years}}$.
Substitute the values from Step 1 and Step 2: $\text{Rate of change}=\frac{114}{4}=28.5$.

Answer:

$28.5$
