To calculate the percent of increase, you can use the 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 $425 and the new value is $467.50.
1. Calculate the difference between the new value and the old value:
\[
467.50 - 425 = 42.50
\]
2. Divide the difference by the old value:
\[
\frac{42.50}{425} \approx 0.1
\]
3. Multiply by 100 to convert to a percentage:
\[
0.1 \times 100 = 10\%
\]
Thus, the percent of increase is **10%**.
The correct answer is **A 10%**.
