Calculate final prices after sales and discounts.
Discount amount = original price × discount %; final price = original price − discount amount.
A $80 item at 30% off saves $24, for a final price of $56.
The discount percentage is applied to the original price, and the result is subtracted to find the final price.
Apply each discount in sequence to the running price to combine multiple offers.
No. Tax is applied after the discount in most regions; add it separately if needed.
