The formula for discount calculations is:
Price x .Percentage = discount
Then you subtract the discount from the price.
(Don't forget the decimal).
Example:
Let's say you want to buy a pair of trousers for £40 and you are given a 30% discount.
£40 x .30 = £12 discount
£40 - £12 = £28
You would pay £28 after the 30% discount on a £40 pair of trousers.
change the percent to a decimal
The discount value is $11.99 and the sale price is $67.99
discount price = price / 2
70 percent is the greater discount.
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%
You could not. You need to know the pre-discount price as well.
The discount value is $11.99 and the sale price is $67.99
discount price = price / 2
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.
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%
15 percent discount of 210 is 31.5.
Percentage discount = 100*(1 - sale price/original price)
You could not. You need to know the pre-discount price as well.
A 50% discount is half off, and a 33.33% discount is one third off.
Convert the discount into a decimal equivalent by removing the percent sign and placing the decimal 2 places to the left of the number in front of the percent sign. (25% = .25; 5% = .05, etc.). Then multiply the number that you want to find the discount for by the decimal equivalent. Example: to find how much 250 with a 15% discount is, multiply 250 x .15 (250 x .15 = 37.50).
I always use a factor of ten. Assume no matter what the discount is it is ten percent to find a ten percent discount just move the decimal point one space to the left, then take that number and subtract it from the original cost. Then in order to find a different percent discount just multiply the ten percent discount by the percent discount you are looking for, but move the decimal one space to the left again, and subtract that from the original cost. Example: something that costs $45 is on sale for 25% off. A ten percent discount would be $4.50. Multiply that by 2.5 to get$11.50. Then subtract that from the original cost to get $33.50. P.S. often times if you don't need the exact answer it is easier to round you numbers to get rid of the .5 to make the math easier.
