Calculate percentage of X, quick & simple.
Let's take a quick example here:
You have a Target coupon of $9910 and you need to know how much will you save on your purchase if the discount is 45 percent.
Solution:
Amount Saved = Original Price x Discount in Percent / 100
Amount Saved = (9910 x 45) / 100
Amount Saved = 445950 / 100
Amount Saved = $4459.5 (answer).
In other words, a 45% discount for a purchase with an original price of $9910 equals $4459.5 (Amount Saved), so you'll end up paying 5450.5.
