问一道题：NO.PZ2018062003000066

问题如下：

Being a monopoly in the market, Googge,Inc. recently carrys out its market study and finds that the price elasticity of demand is 1.8. If the marginal cost is $30 and the average cost is $50, its price is most likely to be:

选项：

$30.

$50.

$68.

解释：

C is correct

When MR = MC, the firm can achieve maximized profits. Because MR =P(1-1/|E|) we can draw the equation:

$30 = P[1 – (1/1.8)] = P × 0.444

P = $68

考题：利润最大化

解析：本题直接考察利润最大化，

直接套用公式，MR =P(1-1/|E|)，代入数据得：

$30 = P[1 – (1/1.8)] = P × 0.444，反解得到P

P = $68

MR =P(1-1/|E|)这个公式可以麻烦再讲解一次怎么得来的吗？谢谢
