Question

During the month of February, Fabulous Feet Shoe Mart sold 50 pairs of red loafers. After an ad campaign to boost sales, they sold 60 pairs in March. Find the percent of increase in sales.

Answer 1

To calculate the percent of increase in sales from February to March, we can use the following formula:

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

In this case:

• Old Value (February sales) = 50 pairs
• New Value (March sales) = 60 pairs

Now, plug these values into the formula:

\[ \text{Percent Increase} = \left( \frac{60 - 50}{50} \right) \times 100 \]

\[ \text{Percent Increase} = \left( \frac{10}{50} \right) \times 100 \]

\[ \text{Percent Increase} = 0.2 \times 100 \]

\[ \text{Percent Increase} = 20% \]

Therefore, the percent of increase in sales from February to March is 20%.
