The only practical reason to calculate the discount is
as an intermediate step in determining the new price.
That means that there is a discount (a price reduction, compared to the "official" price), and that this reduction is calculate as a percentage of the total price.
Cp = sp/d
The quickest way is to multiply the full price by 0.2 That is the amount of the discount.
A discount is subtracted. Suppose something's price was $5 and there was a $1 for that day. You could calculate the price by doing $5 -$1 = $4. The discount is the reduction in price.
It can be helpful to first calculate 10% off by simply moving the decimal over one point. Then you can either multiply that by 4 or double it twice to calculate the amount off. To find the new sale price, take the original price and subtract the discount. For example, 40% off a $24.00 item can be calculated as follows: 10% off: $2.40 Multiply by 4: $9.60 Subtract from original price: $14.40 So the discount is $9.60 and the final price is $14.40.
Discount = Original Price - Discounted Price.Percentage Discount = 100*Discount/(Original Price)
Original price = Sale price + Discount amount
How to calculate sale price if marked price and percent discount are given:First change the percent discount to a decimal.You then multiply the percent discount in decimal form by the marked price.Finally, you subtract the answer from the multiplication problem from the marked price, and get your final answer!
That means that there is a discount (a price reduction, compared to the "official" price), and that this reduction is calculate as a percentage of the total price.
Suppose percent discount is D. Then Marked Price = Sale Price/(1-D/100)
Cp = sp/d
The quickest way is to multiply the full price by 0.2 That is the amount of the discount.
The discount is 15% of 45 = 45*15/100 = 6.75 The sale price is 45 - 6.75 = 38.25.
A discount is subtracted. Suppose something's price was $5 and there was a $1 for that day. You could calculate the price by doing $5 -$1 = $4. The discount is the reduction in price.
