The alternatives are to attend a hockey game, which you value at $30, or to attend a book reading, which you value at $ 15. both are also free.</p><p>翻译</p><p>你已经决定参加一个<strong>免费</strong>的音乐会了。你的另外替补活动方案是参加一个价值$30的冰球比赛，或者是去一个你认为价值$25的地方读书，这两个备选方案也都是<strong>免费</strong>的。</p><p>when you arrive at the rock concert, you are told that there is a fee of $20 to pay for crowd control. Do you pay the $20 and attend the rock concert or just go home? what's your opportunity cost if you attend the rock concert or if you go home? why?</p><p>问：<strong>当你已经到达音乐会的时候</strong>，你被告知这个音乐会不是免费的，而是要收你$20的管理费，那么你应该决定花这$20还是选择回家？这时如果你选择花$20听音乐会的话你的机会成本是多少？如果你选择回家的话你的机会成本是多少？为什么？</p><p></p>
