Final answer:
Class-marketing is an upselling strategy used by businesses to increase demand and revenue.
Step-by-step explanation:
Class-marketing is an upselling strategy used by businesses to increase demand for their products. It involves offering additional products or services to customers to encourage them to spend more money. For example, if a customer is purchasing a laptop, the salesperson may suggest buying a warranty or upgrading the memory for an additional cost.
By implementing class-marketing, companies can not only increase their revenue but also enhance customer satisfaction. When done effectively, class-marketing can help businesses meet their sales targets and build customer loyalty.
