Preguntas frecuentes
How is a discount computed?
final = price × (1 - discount%). 25% on USD 80 leaves USD 60.
Reverse?
discount% = (original - final) / original × 100.
Chained discounts?
Applied sequentially. 10% + 10% = 19%, not 20%.
Does discount include tax?
Depends on the store. Many compute the discount on pre-tax and then add tax.
