Calculate percentage of X, quick & simple.
Let's take a quick example here:
You have a Target coupon of $446 and you need to know how much will you save on your purchase if the discount is 87 percent.
Solution:
Amount Saved = Original Price x Discount in Percent / 100
Amount Saved = (446 x 87) / 100
Amount Saved = 38802 / 100
Amount Saved = $388.02 (answer).
In other words, a 87% discount for a purchase with an original price of $446 equals $388.02 (Amount Saved), so you'll end up paying 57.98.
