Answer: Opportunity cost of returning to college next year is $1,000,000.
Explanation: Opportunity cost is the cost of the next best alternative sacrificed or foregone. When the athlete chooses to join college he is sacrificing his income that could be earned from playing the game. The player has the option of playing for the minor league baseball team for $1,000,000 or for European professional football team for $500,000. The person thus has a choice between playing for the minor league baseball team (since it is the highest paying) or going to college. Thus the opportunity cost of going to college will be $1,000,000.
