24 The short-term breakeven point of production for a firm operating under perfect competition will most likely occur when:A price is equal to average total cost.B marginal revenue is equal to marginal cost.C marginal revenue is equal to average variable costs.1）这一题是怎么的出来的？已知短期盈亏平衡点是AR=ATC，因为任何市场下P=AR，所以P=ATC吗？2）另外我看到原版书上写在完全竞争和非完全竞争下的盈亏平衡点都是AR=ATC，这个对吗？原版书：A firm is said to break even if its TR is equal to its TC. It can also be said that a firmbreaks even if its price (AR) is exactly equal to its ATC, which is true under conditionsof perfect and imperfect competition.3）题目中如果说的average cost是默认为average total cost吗？
