To take a percentage of a price, multiply the price by the decimal equivalent of the percentage, which is the percentage divided by 100.
25 percent of 15.00 = 15 x 0.25 = 3.75
To take a percentage off a price, you can either subtract that number from the original price (15.00 - 3.75 = 11.25) or multiply the original price by the decimal equivalent of 100 percent minus the discount. (15 x 0.75 = 11.25)
Things are greatly simplified if you convert the percentage to a factor. Let me illustrate with an example. If the percentage off is 10%, that means that the sales price is 90% (100% - 10%) of the original price. Convert this to a factor, 0.9 (calculated as 90 / 100).With a little bit of practice, you should be able to get the factor, 0.9, in your head - at least, for integer percentages.
Now, if you have the original price, you can multiply by 0.9 to get the sales price.
Therefore, if you have the sales price, you have to DIVIDE by the same factor - in this example, by 0.9 - to get the original price.
We're gonna tear this up. It's simple, but it will take a bit of patience, so buckle up. Ready? Let's go. You don't know the original price. You know the percent off. You know the sale price. We're in business. Let's hammer this thing. Here's how to work the problem....We don't know the original price, but we know that a percentage of it has been deducted from it (that original price) to give us a sale price, okay? Some percent off the original price is the sale price. Here's the trick. Look at the percent off. Now look at 100% minus the percent off. This new percentage represents how much of the original cost the final cost is. Got it? Another way to say that is that our new (calculated) percentage times the original price equals the sale price. Make sense? Let's pick something easy and give it a test drive.Say something costs $9 (that's the sale price), and it was marked down 10%. That means that the original cost minus 10% of the original cost is the final (the sale) price, or the $9. Now check this out. Focus. The discount was 10%, and another way to look at the problem is that the sale price is 100% -10% of the original price, which says that the sale price is 90% of that original price. Again, the sale price is 90% of the original price. See how that works? We use the discount (percentage) and make a calculation to find out how much of the original price the sale price is. We good? Super.As we now have a "new" set of facts to work with, that is, we have the sale price and the percentage of the original price that the sale price represents, we can go for it. The original price (the unknown) times the percentage of that original price that the sale price represents equals the sale price. Let's look at our example.The original price times the percentage of that price the sale price represents equals the sale price. Again, original price times that percentage we calculated equals the sale price. Now to do some math. If the original price times that new percentage equals the sale price, then the original price equals the sale price divided by the percentage. See what we did? We moved the percentage over to the other side of the equation. We divided both sides by the percentage, and it "dropped out" on the one side and appeared on the other. That's because we needed to isolate the original price (so we could solve for it using the other variables). In our example, the original price equals $9 (the sale price) divided by 90% (the percentage of the original price the sale price represents. $9 divided by 90% equals $9 divided by 0.9 which equals $10. The original price of the item was $10, and it was 10% off. The 10% of $10 equals $1, and the sale price is $10 minus $1 which equals $9. Our work checks.One more problem for fun to lock things in. At a 20% off sale, an item sells for $40 (its sale cost). What was its original cost? We know that the $40 represents 80% of the original price (100% -20%). The original price times the 80% equals $40. The original price equals $40 (the sale price) divided by the 80% (the percentage of the original price that the sale price represents). $40 divided by 80% equals $40 divided by 0.8 which equals $50. Our item's original price was $50. Last thing. $50 times 20% equals $10, and $50 minus $10 equals $40. Our work checks.We good? Excellent!I don't understandexplain more carefully
The original price was $104.00
The answer will depend on what information you do have.
Basically to figure out the percentage of an original price you can either do the following:1) Find out the percentage of the amount you want off then take it away:For example if you wanted 40% of a £30 shirt, you would times the amount by 0.n (n is the percentage). Therefore £30 x £0.40 which is £12.Afterwards you then deduct this from the original amount of £30. So 40% off a £30 shirt the sale price would be £18.2) You could also take away first before multiplying:100% - 40% = 60%£30 x 0.6 = £18NOTE: If you wanted 5% off then you would need to times by 0.05!
Percent of increase is the product of changes in price over the original price with 100%. That is:percent increase = (changes in price/original price) x 100%.For example:In a year period, the price of a stock increased from 50 dollars a share to 59 dollars a share. To find the percent of increase in the share price, compare the change in price to the original price:percent increase = (changes in price/original price) x 100%.= (59 dollars - 50 dollars)/50 dollars x 100%= 18%
original price-sale price. Then original sale price/the answer to the previous.
Discount = Original Price - Discounted Price Percentage Discount = 100* Discount / Original Price
Percentage discount = 100*(1 - sale price/original price)
Take the amount saved, divide it by discount percentage then multiply the result by 100.
Take the sale price from the original price. The difference is the discount. Calculate the discount as a percentage of the original price. This is the 'percentage off'. Example: Original price 100 verdibors Sale price 80 verdibors Discount = 100-80=20 verdibors. So percentage off is 20/100 = 20% ----------------------------------------------------- Calculating percentages: To convert fractions to percentages, multiply the top figure of the fraction by 100, then 'cancel down'. e.g. 1/4 ..... 1/4 x 100= 100/4 = 25 %
The answer depends on what the percentage problem is. The equations will be different depending on whether you want to find:one number as a percentage of another,a given percentage of a number,the percentage change applied to a given number,find the original number if given the number after the percentage change.
first your subtract your original price from the new one to find the difference 2.80-2.45=.35 then divide your difference by the original price .35/2.45 = .1428571429 multiply the answer by 100 to get your percentage .1428571429x100=14.285... round it and you have your answer answer is 14%
You need to know the discounted price and either the discount amount or the discount rate. If you know the discount amount: Original Price = Discounted Price + Discount If you know the Discount Rate (percentage discount ): Original Price = 100*Discounted Price / (100 - Discount Rate)
To calculate the percentage discount, first find the difference between the original price and the final price: 16.95 - 15.96 = 0.99. Then, divide the discount amount by the original price and multiply by 100 to get the percentage discount: (0.99 / 16.95) * 100 β 5.84%.
First we have to find the markup amount, which is the original price times the markup percentage: $64 * 15% This is the same as: $64 * 0.15 = $9.60 Now we add the markup amount to the original price to get the retail price: $64 + $9.60 = $73.60 The retail price is $73.60
you cannot. you need more info.
You check the price tag for the words original price.
