问题如下:
A machine manufacturer is analyzing its cost structure, and here presents the detailed information as following table shows: :
At which quantity level, the manufacturer has the lowest average total cost?
选项:
A.When produces 2 machines.
B.When produces 3 machines.
C.When produces 4 machines.
解释:
C is correct
考点:平均总成本。
解析:第一步要先求总成本即,总固定成本+总可变成本。之后再套用平均成本公式。
在上述方法下,第4个产量下的平均总成本最低,即ATC = TC/Q = 760/4 = 190.
如果只看边际成本的增加量是否可以?除以对应的产量?
