No, successive discounts apply sequentially; 20% off plus 20% off equals 36% total discount, not 40%.
Final Price = Original Price * (1 - Discount 1) * (1 - Discount 2).
Mathematically, the sequence does not matter; (1 - A) * (1 - B) yields identical results in either order.
Calculate sale prices, final checkout cost, dollar savings, and sales tax.
Calculate sales tax, total purchase price, or reverse-calculate pre-tax amount.
Find the original retail tag price before a sale or promotional discount was applied.
