Riverside School District sports budget
Year Per-student budget
2018 $69
2019 $69
2020 $68
2021 $69
2022 $70
According to the table, what was the rate of change between 2020 and 2022?
$ ___ per year

Answer 1

To calculate the rate of change in per-student spending between 2020 and 2022, we need to find the difference in the per-student budget for those two years and then divide by the number of years between them.

The per-student budget for 2020 is $68, and for 2022 it is $70.

1. **Find the difference:**
\[
70 - 68 = 2
\]

2. **Find the number of years:**
From 2020 to 2022 is 2 years.

3. **Calculate the rate of change:**
\[
\text{Rate of change} = \frac{\text{Difference}}{\text{Number of years}} = \frac{2}{2} = 1
\]

So, the rate of change between 2020 and 2022 is **$1 per year**.
