👉 Rebate math involves calculating the final price of an item after a discount is applied, often in conjunction with additional incentives like free shipping or extended warranties. To compute the rebate, first determine the total discount amount by multiplying the original price by the discount rate (expressed as a decimal). Then, subtract this discount from the original price. If there are further incentives, such as free shipping or a warranty discount, apply those sequentially to the reduced price. For example, if an item costs $100 with a 20% discount and free shipping (worth $10), the total rebate is $30 (20% of $100), bringing the final price to $70 ($100 - $30).
