Answer: 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.
I think I must first get the marginal cost of the product before i bought if it is worth it to its value, Then i would compute for the marginal benefit to know what would i gain in this product. Lastly I would compare both the marginal cost and marginal percentage if the cost is lower than the benefit then the product is worth it to buy.
