Marketing works for businesses through the four P's of the marketing mix: product, price, place, and promotion. Product refers to the goods and services that satisfy customer needs. Price is what customers pay, and businesses must determine prices that will sell products successfully. Place involves distributing products in the right locations. Promotion encompasses advertising, selling, sales promotions, and public relations to educate customers about products and services. Together, the four P's ensure a continuous flow of satisfying customer needs through the provision of goods and services in demand.
