Anderson is facing the hardest decision in his life: Should he buy the newest Xbox Series X (cost $500), the newest Apple Airpod Max (cost $550), or the newest Apple Mac Pro Wheels Kit (cost $700). Right now, Anderson has exactly $700. Provided that Anderson already has EVERYTHING he needs and the $700 cannot be used on anything else to make him happier (in other words, the $700 should only be spent on these 3 items. Moreover, for example, if Anderson chooses to buy the Xbox for $500, the remaining $200 is not usable and has no value to Anderson). 1/ If Anderson chooses to buy the Airpod Max, what is the opportunity cost associated with that option? 2/ How would your answer in 1/ change if Anderson just won the $1 million lotteries today? 3/ How would your answer in 1/ change if Anderson just lost one of his $100 bill today, making him now only has $600 left?
