To find the rate of change between March and June, we need to calculate the difference in the savings account balances for those months and then divide by the number of months between them.

**Step 1: Find the balances for March and June.**
- March balance: $75
- June balance: $79

**Step 2: Calculate the difference in balance.**
Difference = June balance - March balance
Difference = $79 - $75 = $4

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

**Step 4: Calculate the rate of change.**
Rate of change = Difference / Number of months
Rate of change = $4 / 3 months = approximately $1.33

Therefore, the rate of change between March and June is approximately **$1.33 per month**.
