Answer 1

To find the rate of change in Bernie's food budget from April to July, we first need to calculate the difference in budget amounts between these two months and then divide it by the number of months between them.

1. **Identify the budget amounts**:
- April: $412
- July: $431

2. **Calculate the difference**:
\[
\text{Difference} = \text{Budget in July} - \text{Budget in April} = 431 - 412 = 19
\]

3. **Calculate the number of months between April and July**:
- From April to July, there are 3 months (May, June, and July).

4. **Calculate the rate of change**:
\[
\text{Rate of Change} = \frac{\text{Difference}}{\text{Number of Months}} = \frac{19}{3} \approx 6.33
\]

Thus, the rate of change in Bernie's food budget from April to July is approximately **$6.33 per month**.
