Question

"During the month of February, Fabulous Shoe Mart sold 50 pairs of red ballet flats. After an ad campaign to boost sales,

they sold 55 pairs in March. Find the percent of change in sales.

Answer 1

To find the percent of change in sales of red ballet flats from February to March which increased from 50 to 55 pairs, we calculate (55 - 50) / 50 × 100%, which results in a 10% increase in sales.

Step-by-step explanation:

The question asks for the percent of change in sales from February to March after an ad campaign at a shoe store. This is a typical problem found in a high school algebra or business math course.

To calculate the percent of change, you use the formula:

Percent of Change = (New Value - Original Value) / Original Value × 100%

In this case, the original number of ballet flats sold was 50, and the new number after the ad campaign was 55. So the percent change can be calculated as follows:

(55 - 50) / 50 × 100% = 5 / 50 × 100% = 10%

Therefore, the percent of change in sales of red ballet flats from February to March is 10%.
