Question

An ivy plant was 21inches long two years later it was 35 inches long.

What was the percentage increase to the nearest hundredth of the length of the ivy

Answer 1

To find the percentage increase in the length of the ivy plant, you can use the following formula for percentage increase:

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

Given:
- Old Length = 21 inches
- New Length = 35 inches

1. Calculate the increase in length:
\[
\text{Increase} = 35 - 21 = 14 \text{ inches}
\]

2. Substitute the values into the formula:
\[
\text{Percentage Increase} = \left( \frac{14}{21} \right) \times 100
\]

3. Calculate \( \frac{14}{21} \):
\[
\frac{14}{21} = \frac{2}{3} \approx 0.6667
\]

4. Multiply by 100 to get the percentage:
\[
\text{Percentage Increase} \approx 0.6667 \times 100 \approx 66.67
\]

Thus, the percentage increase in the length of the ivy plant is approximately **66.67%**.
