Ingrid has been waiting for the show "Mamma Mia!" to come to town. When it finally does come, tickets cost $60. Ingrid's reservation price is $75. But when Ingrid tries to buy a ticket, they are sold out. Suppose Steven was able to purchase a ticket at the box office for $60. Steven's reservation price for the ticket is $65. If Steven attends "Mamma Mia!" and Ingrid does not, then this situation is:

inefficient because Steven and Ingrid could have made a mutually beneficial trade.

Explanation:

Regarding the question, Ingrid was waiting for "Mamma Mia!" show to come to town; it eventually came with tickets cost of $60. Even though Ingrid's reservation price was $75, he was not able to get a ticket as they had been sold out.

On the other hand, Steven got a ticket for $60 even though his reservation price for the ticket was $65. Steven eventually attended "Mamma Mia!" show while Ingrid does not. This is an inefficient situation because Steven and Ingrid should have made a mutually beneficial trade which could have happened if Steven had sold Ingrid the ticket for the show for $70 and they would have been better off.
