Question

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:

Procedure: To calculate the discount%, multiply the rate by the original price. To calculate the sale price, subtract the discount from original price.
