$
permonth

Answer 1

To find the rate of change in Emilia's checking account balance between June and July, we can use the formula:

\[
\text{Rate of Change} = \frac{\text{Balance in July} - \text{Balance in June}}{\text{Number of months}}
\]

Given the balances:
- Balance in June = $56
- Balance in July = $91

Now substituting the values into the formula:

\[
\text{Rate of Change} = \frac{91 - 56}{1} = \frac{35}{1} = 35
\]

Therefore, the rate of change between June and July is **$35 per month**.
