Suppose we have 5 people who might attend up to 2 theatre shows at the local theatre. There's a drama and a comedy. The marginal cost of a seat on any given night is both constant and negligible (you can safely ignore it), so profit maximization and revenue maximization amount to the same thing. Below are the maximum willingness to pay values (a person will pay a price up to that value, but no greater) for a seat for each of the 5 people for the two shows.
