Jason is buying sneakers. He is willing, at most, to pay $100 for a pair. When he arrives at the store, he finds that a nice pair of sneakers that are typically selling for $100 are part of a special promotion; buy 1 get one for half price. So, Jason buys two pairs. What is the consumer surplus (in dollars) from Jason's shopping trip if his willingness to pay for a second pair is a bit less, at $80?
