To calculate the percent increase from 4 to 8, you can use the following formula:
\[ \text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]
In this case, the old value is 4 and the new value is 8. Plugging in the values:
\[ \text{Percent Increase} = \left( \frac{8 - 4}{4} \right) \times 100 \]
\[ = \left( \frac{4}{4} \right) \times 100 \]
\[ = 1 \times 100 \]
\[ = 100% \]
Thus, the percent of increase from 4 to 8 is \(100%\).
