During the month of February, Fabulous Feet Shoe Mart sold 30 pairs of red loafers. After an ad campaign to boost sales, they sold 39 pairs in March. Find the percent of increase in sales.

Question

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%.
