To find the rate of change in the number of straight-A students between 2016 and 2019, we can follow these steps:
1. **Identify the number of students in 2016 and 2019:**
- In 2016, there were 97 students.
- In 2019, there were 100 students.
2. **Calculate the change in the number of students:**
\[
\text{Change} = \text{Number in 2019} - \text{Number in 2016} = 100 - 97 = 3
\]
3. **Determine the number of years between 2016 and 2019:**
\[
\text{Years} = 2019 - 2016 = 3 \text{ years}
\]
4. **Calculate the rate of change per year:**
\[
\text{Rate of change} = \frac{\text{Change}}{\text{Years}} = \frac{3}{3} = 1 \text{ student per year}
\]
Therefore, the rate of change between 2016 and 2019 was **1 student per year**.
