Final answer:
Clue's features reflect cost, quality, and access by using price as a signal of quality.
Step-by-step explanation:
Clue is an app that provides information about restaurants, shops, and galleries, allowing buyers to make choices based on price. In these cases, the price of a product or service on Clue can act as a signal of quality. For example, if a restaurant is expensive on Clue, buyers may assume that the food must be good because it is so costly. Similarly, if a lawyer charges a higher price on Clue, buyers might assume that the lawyer must be better than one who charges a lower price.
