Question 1

How do you calculate a discount?

Accepted Answer

Discount Amount = Original Price × (Discount Percentage / 100). Final Price = Original Price - Discount Amount. For stacked discounts, the additional discount is applied to the already-discounted price.

Question 2

How do stacked discounts work?

Accepted Answer

Stacked discounts are applied sequentially, not added together. For example, 20% off + 10% additional off is NOT 30% off. The first discount reduces the price, then the second discount is applied to the reduced price.
