The discount is the difference (subtraction) between the original price, and the price she actually paid.
She received a discount worth 21.00
Discount = Original Price - Discounted Price Percentage Discount = 100* Discount / Original 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 = Original Price minus Sale price.
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)
Discount = Original Price - Discounted Price.Percentage Discount = 100*Discount/(Original Price)
Receiving an 80% discount means that 80% of the original price is subtracted from the original price. So first we need to calculate the discount which is 80% of 138 which is the same as .80 x 138 = 110.40 Now subtract the discount from the original price: 136.00 - 110.40 = 25.60 So children pay 25.60. Another way to think of this is: If children receive an 80% discount, then they are paying only 20% of the original price. So 20% of 138 is 25.60.
Original price = Sale price + Discount amount
The original price is 100.
Percentage discount = 100*(1 - sale price/original price)
34% discount
128%
Discount = Original price minus selling price = 70.00 - 56.00 = 14.00
