Stacked discounts don't add up
30% off plus an extra 20% off is not 50% off. The second discount comes off the already-reduced price: $100 → $70 → $56, a total discount of 44%.

Questions
How do I calculate a discount?
Multiply the price by the discount as a decimal to get the savings, then subtract it. 30% off $120 saves $36, so the sale price is $84.
Is sales tax charged on the original or discounted price?
In most US states, sales tax applies to the price after a store discount. Manufacturer coupons are sometimes taxed on the full price, depending on the state.
