Question

what is the formula of discount​

Answer 1

Answer:

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

Answer:

Find the original price (for example $90 ) Get the the discount percentage (for example 20% ) Calculate the savings: 20% of $90 = $18. Subtract the savings from the original price to get the sale price: $90 - $18 = $72.
