How do you figure the how much percent was taken off the original price if you only have the original price and the sale price?
Sale price/original price will give you a fraction. The fraction x100 gives you the percentage that the sale price is of the original price.100-(that percentage) gives the percent taken off.
How do you figure out a problem that wants to know the original price and gives you the amount of discount?
Let x equal the original price. Let's say the sale is 25 percent off. That means that 0.75x = the sale price. To find the original price, divide the sale price by the decimal equivalent of 100 minus the discount. Example: You bought an item for 48.00 that was marked as being 20 percent off the original price. The original price was 48.00 divided by 0.80 or 60.00
How do you figure out the price of something that you only know the ending total and the percentage off?
Call the percentage off ' P '. The original price was (sell-price) divided by (1 - .01P)
How do you figure out the original price if you have the current price and the amount of the discount?
Take the current price and add whatever the price that was subtracted off from the discount back to it and you will get the original price. If the current price of an item is $50 and had a 10% discount already taken off then dived 50 by 90% (50 / 0.9) which will give you $55.56 which is the original price before the discount. To check to make sure you did it correct take the original price, $55.56, and multiply it by 10% which will give you 55.56 * 0.1 = 5.56 and subtract that from the original; $55.56 - $5.56 = $50 which is the current price. If you have a calculator you can just enter $55.56 - 10% = $50 to check.
