Question

formula for discount %​

Answer 1

Step-by-step explanation:

The first step of the primary method is to use the formula S = p - rp, where S = sale price, r = discount percentage rate, and p = the original price. Using the alternative method, you look at the remaining percent of the price you'd be paying; for example, 90% is left if 10% is taken off

Answer 2

Discount is a kind of reduction or deduction in the cost price of a product. It is mostly used in consumer transactions, where people are provided with discounts on various products. The discount rate is given in percentage.

Discount=ListPrice−SellingPrice

Therefore

SellingPrice=ListPrice−Discount

ListPrice=SellingPrice+Discount

Discount Percentage Formula

RateofDiscount=Discount%=DiscountListPrice×100

SellingPrice=ListPrice(100−discount%100)

ListPrice=SellingPrice(100100−discount%)
