percent

Answer 1

To calculate the percent increase in the length of the ivy plant, you can use the formula:

\[
\text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100
\]

In this case:

- Old Value = 11 inches
- New Value = 18 inches

Now, substitute the values into the formula:

\[
\text{Percent Increase} = \left( \frac{18 - 11}{11} \right) \times 100
\]

Calculate the difference:

\[
18 - 11 = 7
\]

Now substitute this back into the formula:

\[
\text{Percent Increase} = \left( \frac{7}{11} \right) \times 100 \approx 63.63636364
\]

Rounding to the nearest hundredth, the percent increase is:

\[
\approx 63.64
\]

So the final answer is:

**63.64** percent.
