Question

为什么 MC=MR
Profit maximisation
Marginal cost (MC) can be used together with marginal revenue (MR) to show the level of output that leads to profit maximisation; the most profit possible for a firm.
MC = the change in total cost by producing one extra unit of output
MR = the increase in total revenue from selling one extra unit of output
Profit maximisation can be calculated where MC=MR On the table below profit maximisation occurs when the level of output is 7.Even though the addition to total profit is zero,it is important to remember that normal profit is included as a cost.

Answer 1

MC=MR是利润最大化的条件,如果MC>MR,那么生产出最后一个单位的产品的成本比收益大,因此要缩减生产；反之,若MC
