You multiply the price by .10 and then subtract it from the original price:
Here's an example:
79.99*.10=7.99
79.99-7.99=72
I hope this helps!

You would take the price of your item, and multiply is by .1 (which is 10% in decimal form).
Ex. $69.99 * .1 = 6.99 This is the amount you save.
Then you take the amount you save and subtract that from the original total.
$69.99-6.99= $63
OR....you can also multiple your item price by (90%) or .9 in order to get the finalized price without having to subtract.
Ex. $69.99 * .9 = $63 (Notice how they're the same)
P.S. I sorta rounded the answers b/c there's no such thing as $62.991, etc.
After all this you might notice that the amount you save (if its 10%) is the same as moving the decimal place to the left. (This way you wont have to use a calculator or written math)...Also, if you were doing 15% for example, you could just find 10% and then add half of the next 10% to get 15%

The quickest way to do it is to say that you are only paying 90% percent of the price.In your head for the first example you could say 9*7=63 and for the second
9*8=72.If you live in a country which still uses cent coins you can take the cent from these two answers because 90% of one cent is approximately one cent.

Method 1: You are taking 10% off; therefore, you are paying for 90%.
90% (69.99) = .90(69.99) = 62.99
Method 2: What is 10% of 69.99?
10% (69.99) = .10(69.99) = 7.00
Now subtract 7.00 from 69.99
69.99 - 7.00 = 62.99

take the original cost, and multiply it by the decimal form of the percent ( .1= 10%) then take the answer and subtract it from the original price to get the price of the item when you use your discount

first you take the price and multiply it by .10 or 10%. Then that answer you get must be subtracted from the orginal price. This answer is how much it will cost.

100% - 10% = 90% = 90/100 = 9/10 = 0.9
$79.99*0.9 = $71.99
$69.99*0.9 = $62.99

First take the price 69.99 and multiply it by 10% which is 0.10. take that number and subtract it from the price of 69.99.
69.99 x 0.10= 6.999 - 69.99= 62.99 is the price with discount

You will pay 90% of the cost. Rounded up to $70 dollars you would sub. $7. and pay $63. (plus tax, if any).

Amount you pay will be 90% of the cost.
So .90 x 69.99 = 62.99
.90 x 79.99 = 71.99
