To calculate the percentage increase from $25 to $30, you can follow these steps:
1. Determine the increase in price:
\[
\text{Increase} = \text{New Price} - \text{Old Price} = 30 - 25 = 5
\]
2. Convert the increase to a percentage of the old price:
\[
\text{Percentage Increase} = \left( \frac{\text{Increase}}{\text{Old Price}} \right) \times 100 = \left( \frac{5}{25} \right) \times 100
\]
3. Calculate the percentage:
\[
\text{Percentage Increase} = 0.2 \times 100 = 20\%
\]
Thus, the percentage increase when a $25 item is sold for $30 is **20%**.
