Calculate percentage of X, quick & simple.
Let's take a quick example here:
You have a Target coupon of $3229 and you need to know how much will you save on your purchase if the discount is 80 percent.
Solution:
Amount Saved = Original Price x Discount in Percent / 100
Amount Saved = (3229 x 80) / 100
Amount Saved = 258320 / 100
Amount Saved = $2583.2 (answer).
In other words, a 80% discount for a purchase with an original price of $3229 equals $2583.2 (Amount Saved), so you'll end up paying 645.8.
