1) What is 80 percent off £21? Find the amount of discount.
Suppose you have a Kohls coupon of £21 and you want to know how much you will save for an item if the discount is 80 percent.
Replacing the given values in formula (a) we have:

Amount Saved = 1680 / 100
Amount Saved = £16.8 (answer).
In other words, a 80% discount for a item with original price of £21 is equal to £16.8 (Amount Saved).
Note that to find the amount saved, just multiply it by the percentage and divide by 100.

Sale Price = £4.2 (answer).
This means the cost of the item to you is £4.2.
You will pay £4.2 for a item with original price of £21 when discounted 80%.
In this example, if you buy an item at £21 with 80% discount, you will pay 21 - 16.8 = 4.2 pounds.

16.8 = 21 x Discount in Percent / 100
16.8 / 21 = Discount in Percent /100
100 x 16.8 / 21 = Discount in Percent
1680 / 21 = Discount in Percent, or
