Answer:
Price discrimination
Step-by-step explanation:
Price discrimination is a method used by various firms; it is a selling system that charges clients different costs for similar items. They charge clients different prices and the prices depend on whatever the customer can pay. In unmodified price discrimination, the dealer charges every client the most extreme value the individual customer can pay. Under the Robinson-Patman Act of 1936, it is illegal to sell the same quality of products at different prices.
