What is the percent of change for a sweater that is discounted from $44 to $35.20?

Subtract the 2 numbers.
44 - 35.20 = 8.8

Divide this by the original number (The number without the discount), then multiply by 100.

8.8 / 44 * 100 = 20

The difference by percentage is 20%

% change = difference(original-discount price) divided by original number x100

% change = (8.8 / 40) x 100

% change = 22%
