Single discount: Final = Price × (1 − d/100). Double discount: Final = Price × (1 − d₁/100) × (1 − d₂/100). Savings = Original − Final.
Questions fréquemment posées
How do I calculate a percentage discount?
Multiply the original price by (1 − discount/100). For example, 20% off $50: $50 × 0.80 = $40.
Are two 20% discounts the same as one 40% discount?
No. Two sequential 20% discounts give 1 − (0.8 × 0.8) = 36% total discount, not 40%. The second discount applies to the already-reduced price.
What is a BOGO deal?
BOGO stands for 'Buy One, Get One.' You pay full price for the first item and get the second at a discounted rate (often free, i.e. 100% off the second item).
