A rock star intentionally sets her ticket prices below what would be necessary to sell out her shows. how might this be justified by a manager whose goal is to maximize long-term profit?

the answer to this question is: The revenue sacrificed represents a very small share of the show's revenue

The only way the show can still earn profit by selling cheap tickets is if they're gaining additional revenue from another streatm of income, such as selling merchandise on the concerts, providing beer and snacks, or selling autograph and photos
