4. Coco is the winner of the 2023 U.S. Open. After winning, she received $3,000,000 as a reward. Reconsider the previous question. What can you say about the opportunity cost of movie-going for Coco? (1 point) (a) increased: since now that she's won one tournament she knows that she can win more tournaments and money. On top of that, movies are long, so she is never going to the movies again. (b) decreased: because she's already received $3M out of the whole stream of prizes she could win as a tennis player. (c) remained the same: training. (d) none of the above.
