[willie1987 (威力是也)]

N.Inc.,currently produces 110,000 untis at a cost of $440,000.Next year N.Inc.
expects to produce 120,000 units.N.'relevant range is 100,000 to 120,000 units.
If the cost is variable and 120,000 units are produces,the cost:
  (A)will stay the same                (B)will increase to $480,000
  (C)will decrease                     (D)will be indeterminate
  (E)non of the above.

   答案:(D)   我不太懂為什麼從110,000>120,000 成本不能提升到$480,000阿?
              他不是變動成本嗎!?
