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. ingrid decides to try to buy a ticket from a scalper (a person who purchased extra tickets at the box office with the intent to resell them at a higher price). if ingrid finds someone who is willing to sell her a ticket for $70, she should: not purchase the ticket because it is overpriced. not purchase the ticket because the cost to the scalper was only $60. purchase the ticket because doing so will make her $5 better off. purchase the ticket even though doing reduce total economic surplus.
