Maximizing Profit

The last significant value that managers desire to maximize is profit. Recall that:

利润（P）= TR -TC,

要么

P*Q- （（（AQ+C)

宣布边际收益目的等于零优化利润的值。占据盈利角色的第一个衍生品需要以相同的方式将收益的第一个衍生物和总成本功能采用：

Mp = MR - MC,

要么

MR = MC

This last equation is one of the beginning regulations and neatest applications of microeconomics for real-world managers. It states that income is maximized when a company produces a level of production such that the incremental proceeds earned on producing the next unit is equivalent to the incremental cost incurred of producing the next unit. Since producing one unit more would product in the company incurring an incremental cost greater than the incremental revenue advantage from advertising that unit, the company should limit manufacture to the number of units that makes its unimportant profit equation equivalent to zero.
