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!
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)
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.
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% .
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...
The discounted price will be = original price x (100 - %discount) / 100
If the discounted price is $35, then you must reverse the process to find the original price. The original price would be 38.99 dollars.
$25.50 would be the 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.
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
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%
Discounted price was 360 (306/.85)Original price was 400 (360/.9)
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.
It is 100*(1 - Discounted price/Full price) or 100*Discount amount/Full price
$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
Discount = 20% means the discounted price is 80% (100-20) of the original price. 80% of 419.95 = 419.95*80/100 = 335.96
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% .
