Washington School District sports budget
Year Per-student budget
2020 $88
2021 $96
2022 $92
2023 $68
2024 $66
According to the table, what was the rate of change between 2020 and 2021?
$
peryear

Answer 1

To find the rate of change in the per-student budget between 2020 and 2021, you can use the following formula:

\[
\text{Rate of Change} = \frac{\text{Value in 2021} - \text{Value in 2020}}{\text{Year difference}}
\]

Substituting the values from the table:

- Value in 2021: $96
- Value in 2020: $88
- Year difference: \(2021 - 2020 = 1\)

Now, let's calculate it:

\[
\text{Rate of Change} = \frac{96 - 88}{1} = \frac{8}{1} = 8
\]

Thus, the rate of change between 2020 and 2021 was **$8 per year**.
