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.
The discount must be calculated first to get the base price of the item, then the tax percentage would be taken into consideration, otherwise you would be charging additional tax on an item which should be discounted in the first place. If you were to calculate tax first then the discount price, your total would be incorrect.
Cp = sp/d
The quickest way is to multiply the full price by 0.2 That is the amount of the discount.
The only practical reason to calculate the discount is as an intermediate step in determining the new price.
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!

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.
