18%


35%


30%


23%

Answer 1

To find the percent of increase in sales, you can use the following formula:

\[
\text{Percent Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100
\]

In this case:

- Old Value (February sales) = 30 pairs
- New Value (March sales) = 39 pairs

Now, plug in the values:

\[
\text{Percent Increase} = \frac{39 - 30}{30} \times 100
\]

\[
= \frac{9}{30} \times 100
\]

\[
= 0.3 \times 100
\]

\[
= 30\%
\]

Therefore, the percent of increase in sales is **30%**.

The correct answer is **30%**.
