Kristi's parents have increased their contributions to her Education Savings Plan from 128 to 440 per month. What is the percentage increase?

To find the percentage increase in Kristi's parents' contributions, we use the formula:

\[
\text{Percentage Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100
\]

Substitute the values:

\[
\text{Percentage Increase} = \frac{440 - 128}{128} \times 100
\]

Now, calculating the values:

\[
\text{Percentage Increase} = \frac{312}{128} \times 100 \approx 243.75\%
\]

So, the percentage increase is approximately **243.75%**.
