To calculate the percent change from 2 to 3, you can use the formula for percent change:
\[ \text{Percent Change} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]
In this case, the old value is 2 and the new value is 3. Plugging in these values gives:
\[ \text{Percent Change} = \left( \frac{3 - 2}{2} \right) \times 100 = \left( \frac{1}{2} \right) \times 100 = 50% \]
So the percent change from 2 to 3 is 50%.
