Final answer:
A trade discount is a discount offered to encourage prompt payment.
Step-by-step explanation:
A trade discount is a discount offered to encourage prompt payment. It is a reduction in the selling price of a good or service provided by a seller to a buyer. This type of discount is commonly offered to businesses by their suppliers and is typically expressed as a percentage off the list price. For example, if a supplier offers a 10% trade discount on a product with a list price of $100, the buyer would only have to pay $90.
