✔ 最佳答案
(a) profit level係唔係即係profit?
如果係既話,
Profit level
=$100(10-8)
=$200

(b) Marginal cost (MC)
=Total cost of producing 101 units - Total cost of producing 100 units
[=Total cost of producing (n+1) units - Total cost of producing n units]
=$[(8x101+200)-(8x100+200)]
=$8

(c) Variable cost
=$(8x100-200)
=$600

(d) In a competitive market, average revenue(AR)=marginal revenue (MR)
In this case, MR=AR=$10, MC=$8
Since MR>MC, the firm can increase its profit by increasing the output.
Therefore, the efficient scale of the firm is more than 100 units.
