时间Mon Nov 2 02:30:36 2009
抱歉
我本身完全没有学过这方面的学科
麻烦大家帮忙!!
题目:
Tai-power Co. is considering two different materials for use in electricity
generation. Thecosts are shown below. Use present worth to decide
which material should be selected, at an interestrate of 10% per year.
Material JX Material KZ
First cost, $ -205,000 -235,000
Maintenance cost, $/year -29,000 -27,000
Salvage value, $ 2,000 20,000
Life, years 2 4
我的问题:
用最小公倍数来求「残值」究竟要不要重复计算?在哪里计算?
两种材料成本计算是这样吗?(数值暂且除以一千)
Year JX KZ
0 -205 -235
1 -29 -27
2 -205-29+2 -27
3 -29 -27
4 -29 -27+20
真的拜托大家,我已经查了两个钟头了.....感谢!
