 What is 25 percent (%) off $21?

Using the formula one and replacing the given values:

Amount Saved = Original Price x Discount % / 100. So, 
Amount Saved = 21 x 25 / 100 
Amount Saved = 525 / 100

Amount Saved = $5.25

irspow
percent means literally per one hundred so

n(25/100)=21  multiply both sides by 100

25n=2100  divide both sides by 25

n=$84.00
