标题[作业] 总成本 & 边际成本
时间Sun Nov 4 13:37:20 2012
学校:
教师:
科目: 个体经济
题目:
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
※请计算 TC 与 MC
我的想法:
之前写的题目都是有给予确切的成本函数，
老师改成这样的题目实在有点没头绪，
还请各位帮忙一下，谢谢

1F：推 hotcom:定义没变阿，只是间段型资料怎会不知？ 11/04 14:22
2F：→ NTUpope:brother, 你知道函数有分连续函数和非连续函数吗... 11/04 14:38
3F：推 moondark92:机会成本的题目喔...... 11/04 22:36
4F：推 moondark92:生产函数 Q=5.5t-0.5t^2 XDD 11/04 22:50
5F：推 moondark92:连续dQ/dT=5.5-t, 不连续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
