邊際成本 - 經濟

學校:FCU

教師:吳朝欽

科目:經濟學

題目:

Marginal cost equals:

(i) change in total cost divided by change in quantity produced

(ii) change in variable cost divided by change in quantity produced

(iii) the avarege fixed cost of th current unit

(A) (i) and (ii)

(B) (ii) and (iii)

(C) (i) only

(D) All of the above are correct.


我的想法:

我個人覺得是(C)

但是答案卻是(A)

因為邊際成本的話

不是應該△Total Costs/△Quantity才對嗎??

還有請各位了.....
