The formula for discount calculations is:
Price x .Percentage = discount
Then you subtract the discount from the price.
(Don't forget the decimal).
Let's say you want to buy a pair of trousers for Â£40 and you are given a 30% discount.
Â£40 x .30 = Â£12 discount
Â£40 - Â£12 = Â£28
You would pay Â£28 after the 30% discount on a Â£40 pair of trousers.
The discount value is $11.99 and the sale price is $67.99
discount price = price / 2
Divide the discounted by full prices
Percent of discount is the percentage of a whole price that is taken off as a discount.
3.29 is 30 percent percent discount of 10.97.
70 percent is the greater discount.
15 percent discount of 210 is 31.5.
Discount divided by original price gives you a decimal which you then multiply by 100. This equals percent of discount Eg: $15 discount, $80 original price 15 / 80 = 0.1875 x 100 = 18.75%
A 50% discount is half off, and a 33.33% discount is one third off.
Percentage discount = 100*(1 - sale price/original price)
You could not. You need to know the pre-discount price as well.
