Step-by-step explanation:
The essential variables in the marketing of therapeutic recreation services are price, promotion, product, and place. These four variables are often referred to as the 4 Ps of marketing. They are crucial in determining how a service is perceived by potential consumers and how it is sold. Pricing strategies must consider the cost of providing the service, competition, and the perceived value to the consumer. Promotion involves communication strategies to raise awareness of the service. The product, in this context, is the therapeutic recreation service itself, which must be designed to meet the needs of the target population. Lastly, place or distribution pertains to how the service is delivered, which could involve the location of facilities or channels for accessing the service.
