In early July, Colin Marks purchased a $70 ticket to the December 15 game of the Sarasota Shippers. Parking for the game was expected to cost approximately $22, and Marks would probably spend another $15 for a souvenir program and food. It is now December 14. The Shippers were having a miserable season and the temperature was expected to peak at 5 degrees on game day. Marks therefore decided to skip the game and took his wife to the movies, with tickets and dinner costing $50. The sunk cost associated with this decision situation is:

		$70.
		$20.
		$50.
		$107.
		None of the answers is correct.
