Question

percentage increase for 0.48 to 4.39, answer should be rounded to nearest tenth

Answer 1

To calculate the percentage increase from 0.48 to 4.39, you can use the following formula:

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

Plugging in the values:

- Old Value = 0.48
- New Value = 4.39

\[
\text{Percentage Increase} = \left(\frac{4.39 - 0.48}{0.48}\right) \times 100
\]

Now, calculate it step by step:

1. Subtract the old value from the new value:
\[
4.39 - 0.48 = 3.91
\]

2. Divide by the old value:
\[
\frac{3.91}{0.48} \approx 8.14583333
\]

3. Multiply by 100 to get the percentage:
\[
8.14583333 \times 100 \approx 814.5833333
\]

4. Round to the nearest tenth:
\[
\approx 814.6
\]

Thus, the percentage increase from 0.48 to 4.39 is approximately **814.6%**.
