To calculate the percent increase, you can use the formula:
\[
\text{Percent Increase} = \left( \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \right) \times 100
\]
In this case, the old price is $50 and the new price is $62.50.
1. Calculate the change in price:
\[
\text{Change} = 62.50 - 50 = 12.50
\]
2. Divide the change by the old price:
\[
\frac{\text{Change}}{\text{Old Price}} = \frac{12.50}{50} = 0.25
\]
3. Convert to a percentage:
\[
0.25 \times 100 = 25\%
\]
Thus, the percent increase is **25%**.
The answer is **A**.
