In early July, Michael Bluth purchased a $70 ticket to the December 15 game of the Chicago Titans; the Titans belong to the Midwest Football League and play their games outdoors on the shore of Lake Michigan. Parking for the game is expected to cost approximately $22, and Michael would probably spend another $15 for a souvenir program and food. It is now December 14. The Titans were having a miserable season and the temperature is expected to peak at 5 degrees on game day. Michael is thinking about skipping the game and taking his wife to the movies and dinner, at a cost of $50. The amount of sunk cost in Michael's decision to spend some time with his wife is:

A) $0

B)

$70

C)

$50

D)

$20

E)

$107

F)	None of the above

I don't think it's 50 like the other question said so if you say it's 50 please let me know why you get that.
