1 answer

To calculate the percent increase, you can use the formula:

\[ \text{Percent Increase} = \frac{\text{New Price} - \text{Original Price}}{\text{Original Price}} \times 100 \]

In this case, the original price is $20 and the new price is $25. Plugging in these values:

\[ \text{Percent Increase} = \frac{25 - 20}{20} \times 100 = \frac{5}{20} \times 100 = 0.25 \times 100 = 25% \]

So, the percent increase is D) 25%.
