標題[作業] 總成本 & 邊際成本

科目: 個體經濟
題目:
Zoe is trying to decide how to divide her time between her job as a wedding
photographer, which pays $27 per hour for as many hours as she chooses to
work, and as a fossil collector, in which her pay depends both on the price
of fossils and the number of them she finds. Earnings aside, Zoe is
indifferent between the two tasks, and the number of fossils she can find
depends on the number of hours a day she searches, as shown in the table
below:
Hours per day Total fossils per day
１ ５
２ ９
３ １２
４ １４
５ １５
※請計算 TC 與 MC
我的想法:
之前寫的題目都是有給予確切的成本函數，
老師改成這樣的題目實在有點沒頭緒，
還請各位幫忙一下，謝謝

1F：推 hotcom:定義沒變阿，只是間段型資料怎會不知？ 11/04 14:22
2F：→ NTUpope:brother, 你知道函數有分連續函數和非連續函數嗎... 11/04 14:38
3F：推 moondark92:機會成本的題目喔...... 11/04 22:36
4F：推 moondark92:生產函數 Q=5.5t-0.5t^2 XDD 11/04 22:50
5F：推 moondark92:連續dQ/dT=5.5-t, 不連續dQ/dT=5-t 11/04 22:55
6F：→ moondark92:更正: 6-t 11/04 22:56
7F：→ moondark92:MC= 27xdT/dQ = 27/(5.5-t) 或 27/(6-t) 11/04 22:57
8F：推 moondark92:T=5.5-(30.25-2Q)^0.5 11/04 23:25
9F：→ moondark92:MC(Q)=27/[(30.25-2Q)^0.5] 11/04 23:26
10F：推 moondark92:TC(Q)=27T=148.5-27x(30.25-2Q)^0.5 11/04 23:30
