To find the rate of change between the years 2020 and 2021, we first need to determine the number of straight-A students in each of those years from the data provided:
- Students in 2020: 63
- Students in 2021: 34
Next, we calculate the change in the number of students from 2020 to 2021:
\[
\text{Change} = \text{Students in 2021} - \text{Students in 2020} = 34 - 63 = -29
\]
Now, we find the rate of change, which is the change divided by the number of years:
\[
\text{Rate of Change} = \frac{\text{Change}}{\text{Number of Years}} = \frac{-29}{1} = -29
\]
Thus, the rate of change between 2020 and 2021 is \(-29\) students per year.
- Students in 2020: 63
- Students in 2021: 34
Next, we calculate the change in the number of students from 2020 to 2021:
\[
\text{Change} = \text{Students in 2021} - \text{Students in 2020} = 34 - 63 = -29
\]
Now, we find the rate of change, which is the change divided by the number of years:
\[
\text{Rate of Change} = \frac{\text{Change}}{\text{Number of Years}} = \frac{-29}{1} = -29
\]
Thus, the rate of change between 2020 and 2021 is \(-29\) students per year.
