You have just won a radio contest and are disappointed to learn that the prize is four tickets to the Def Leppard reunion tour (face value $40 each). Not being a fan of 1980s power rock, you have no intention of going to the show. However, the radio station offers you another option: two tickets to your favorite band’s sold-out show (face value $45 each). You notice that, on StubHub, tickets to the Def Leppard show are being bought and sold for $30 apiece and tickets to your favorite band’s show are being bought and sold at $50 each. What should you do?
