问题如下：
Upsilon Natural Gas, Inc. is a monopoly enjoying very high barriers to entry. Its marginal cost is $40 and its average cost is $70. A recent market study has determined the price elasticity of demand is 1.5. The company will most likely set its price at:
选项：
A. $40.
B. $70.
C. $120.
解释：
C is correct.
Profits are maximized when MR = MC. For a monopoly, MR =P(1-1/|E|) Setting this equal to MC and solving for P:
$40 = P[1 – (1/1.5)] = P × 0.333
P = $120
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：
$40 = P[1 – (1/1.5)] = P × 0.333
P = $120
是否还在新考纲内容，谢谢
