B.ProjeA because its Eis higher. C.ProjeB because its Eis higher. C is correct.考点Mutually Exclusive Projects with fferent Lives解析在选择不同期限的互斥项目时,我们可以使用EAA法。先计算出每一个项目的NPV,再根据算出的NPV来计算PMT,从而挑选一个能给我们带来等效年金最大的项目。NPVA = -130,000 +∑t=1350,0001.12t+50,000+30,0001.124\sum_{t=1}^3\frac{50,000}{1.12^t}+\frac{50,000+30,000}{1.12^4}∑t=131.12t50,000+1.12450,000+30,000 = $40,933.01 PV = -40,933 , N=4 , I/Y=12 , FV=0 CPT→PMTA = 13,476.56 NPVB = -85,000 + ∑t=1245,5001.12t\sum_{t=1}^2\frac{45,500}{1.12^t}∑t=121.12t45,500 +45,500+20,5001.123\frac{45,500+20,500}{1.12^3}1.12345,500+20,500 = $38,874.82 PV = -38,874.82 , N=3 , I/Y=12 , FV=0 CPT→PMTB = 16,185.49 因为项目B的EAA较大,所以我们应该选择项目 老师,我脑子老是混淆mutuexclusive project和expansion project,因为咱们讲expansion project的时候,最后一期现金流是=OCF+TNOCF=OCF+WC+St-T*(St-Bt),这里是怎么理解after-tsalvage就是最后一期的TNOCF呢?
NO.PZ2018101501000023 如题,两种都算了算,答案倒是可以选对。
NO.PZ2018101501000023 老师您好,这道题我过程都懂的,但有个点,就是EEA 取值的时候,按照解题思路给的是 PV = -40,933 , N=4 , I/Y=12 , FV=0 CPT→PMTA = 13,476.56 但我自己算的时候,用FV = 40,933 , N=4 , I/Y=12 , PV=0 CPT→PMTA = -8564.59, 分别计算后,我也得出了 PMT b 大于 PMT a 这个结果。 最后是选对了,我就想确认下,这种方法只是我碰巧做对了,还是两种都可以, 谢谢!

NO.PZ2018101501000023 只是说我们的单纯的求NPV而已, 和expansion proje里面的公式是咩有关系的对吗?
