The discount is the difference (subtraction) between the original price, and the price she actually paid.
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.
To find the discount rate, subtract the sales price from the original price to determine the discount amount. Then, divide the discount amount by the original price. Finally, multiply the result by 100 to convert it into a percentage. The formula can be summarized as: Discount Rate (%) = [(Original Price - Sales Price) / Original Price] × 100.
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.
To find the discount price on a commodity, first determine the original price and the discount percentage. Multiply the original price by the discount percentage (expressed as a decimal) to find the discount amount. Subtract this discount amount from the original price to obtain the discount price. For example, if an item costs $100 and has a 20% discount, the discount amount is $20, making the final price $80.
The formula for calculating the rate of discount is: [ \text{Rate of Discount} = \left( \frac{\text{Discount Amount}}{\text{Original Price}} \right) \times 100 ] This formula expresses the discount as a percentage of the original price, where the discount amount is the reduction in price from the original price to the sale price.
Percentage discount = 100*(1 - sale price/original price)
