Formula and calculation method
Savings equal original price multiplied by the discount rate; sale price equals original price minus savings.
Worked example and assumptions
A 20% discount on $100 saves $20 and gives an $80 sale price before tax and shipping. Two successive 20% discounts equal 36%, not 40%.
