Terms to know:
List price: Regular price of an item.
Discount: A reduction made from the regular price
Sale price: The reduced cost of an item
Discount rate: Percent that the price is reduced.
To find a sale price, use the following formulas:
Sale price = List Price − Discount
Discount = (List Price) × (Discount Rate)
Exercise # 1:
Find the sale price for an item that has a list price of 100 dollars and a discount rate of 25%
Discount = 100 × 25% = 100 × 0.25 = 25
Sale price = List Price  Discount Price = 100  25 = 75 dollars.
Exercise # 2:
Find the sale price of an item that has a list price is 24 dollars and a discount rate of 50%
Discount = 24 × 50% = 24 × 0.50 = 12
Sale Price = List Price  Discount = 24 − 12 = 12 dollars.
Exercise # 3:
Find the sale price of an item that has a list price is 27 dollars and a discount rate of 33.33333%
Discount = 27 × 33.33333% = 27 × 0.3333333 = 8.9999999
Sale Price = List Price  Discount = 27 − 8.9999999 = 18.0000001 dollars.
