How do you calculate percentage off of something?

I'm trying to find out how how much a game would be if you take 20 percent off.



For example

20% off of $17.99





It'd also be nice if someone could tell me how to do this both on paper and in MS Excel.How do you calculate percentage off of something?
the game with the discount will cost $14.39



--------------------------------------鈥?br>


20% as a decimal is 0.2 (to find the decimal, divide the percentage by 100)



on a calculator type in



0.2 x 17.99

= 3.598



then take that from the price



17.99 - 3.598 = $14.39



--------------------------------------鈥?br>


on excel you can just type into the box this

=17.99*20%How do you calculate percentage off of something?
.20 * 17.99 = 3.598



17.99 - 3.60 = 14.39 total cost



just multiply the 17.99 * 20%
