1) What can we infer about the marginal benefit of a movie ticket for a moviegoer who sits in the Sightline section before and after the upcharge?
Before the price rise, marginal benefit ____________ price, and after the price rise, marginal benefit ____________ price.
Wrong! - If a moviegoer buys a movie ticket, what is the relationship between marginal benefit and price?
Correct! - A moviegoer will buy a movie ticket only if the marginal benefit exceeds or equals the price. The moviegoer buys a ticket before and after the rise in price, so it must be the case that marginal benefit exceeds price before the price rise, and marginal benefit exceeds or equals price after the price rise.
