※ 引述《yamitigo (鴨米鐵劍)》之銘言: : 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 △TC MC = ------ ,在微量變動時, MC = dTC/dQ △Q : (ii) change in variable cost divided by change in quantity produced TC = TVC + TFC dTC/dQ = d(TVC+TFC)/dQ = dTVC/dQ + dTFC/dQ 然後dTFC/dQ 會等於0 所以 dTC/dQ = dTVC/dQ : (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..... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.130.198.137
