I assume you're doing this for school, so I'll explain the answer.

If it's 20% off, then it's 80% of the original price (100% is full price). Let's call the original price P, for Price. 80% of something is the same as multiplying that something by .8 (since you can always multiply something by one, and .8 is 80% of 1).

Eighty percent of the original price is $16.80, thus .8 (P) = $16.80

You need to solve for P, so you need to get P by itself on one side. The easiest way is to get rid of the .8. Divide both sides by .8 and you get P = $16.80/.8, or $21.00, so the original price (P) is $21.00

To check this, get a calculator and solve for 80% of 21.00 (if you don't have a percent sign, just type 21.00*.8). Hope this helped!

How do you find the original price knowing only the discounted price and discount?

Example- Discount Price= $22.80 Percent/ Discounted Price= 40% Find out first how much 40% from 100% is? = 60% Formula- $22.80 x 100/60 = $38.00

Discounted price was 360 (306/.85)Original price was 400 (360/.9)


How do you take a percent off of a dollar amount?

One way:-- Subtract the discount percent number from 100 .-- Multiply the result by the dollar amount.-- Divide the result by 100 .-- The result is the discounted amount.===============================Another way:-- Multiply the dollar amount by the discount percent number.-- Divide the result by 100 .-- Subtract the result from the original dollar amount.-- The result is the discounted amount.


Why is 20 percent off an item plus an additional 20 percent off not 40 percent?

Because the second discount refers to the already-discounted price, not to the original full price. Example: -- The item was originally priced at $100. -- It was discounted 20%, and that brought its price down to $80. -- If it's discounted again later, then the second 20% discount will be 20% of $80, not 20% of $100. 20% of $80 is $16, so the second discount will reduce the price to $64. -- If it had been reduced from $100 all the way to $64 in one cut the first time, that discount would have been 36% .


A 5 percent discount of an item and subsequent 3 percent discount is the same overall 8 percent discount?

Not necessarily. It depends on whether the 3% is based on the already discounted price or the original full price: eg original price 100, less 5% = 95. Taking 3% off this is a further 2.85 giving a new nett of 92.15. A straight 8% would leave 92 exactly...

15 percent off 680 what is the original price?

You seem to be saying that 15% off gives a discounted price of 680, and asking what the original price was before the discount. Since the price was discounted by 15%, the discounted price is 85% of the original price. Dividing 680 by 0.85 gives 800 as the original price.

When multiple discounts are used if an item is first discounted by 40 percent then again by 30 percent and again by 10 percent the final or cumulative discount is off the original price?

Discount #1 = 40% Discount #2 = (100% - 40%) X 30% = 18% Discount #3 = (100% - 40% - 18%) X 10% = 4.2% Total discount off the original price = 40% + 18% + 4.2% = 62.2%

What is the original price with a 20 percent discount you get 249.99?

$312.49 ; here's how: You have original price is 100%, final price = original price - discount amount, and discount amount = original price * discount percent.So Final price = original price - original price * discount percent = (Original price)*(100 % - discount percent).249.99 = P0 * (100%-20%) = P0 * (0.80) ---> P0 = 249.99 / 0.80 = 312.4875
