同学你好，这道题目问的是，一个分析师希望在五年后，net sales变成两倍，net income变成三倍。求一个年化的复利的增长率。所以我们假设现在的net sales为1，那么五年后就变成2，相当于就是求1*(1+r)^5=2其中的这个r; net income 也是这样，假设现在的net income为1，那么五年后就变成3，相当于就是求1*(1+r)^5=3其中的这个r。如果用计算器的话，对于net sales来说，N=5；PV=1；PMT=0；FV=-2；CPT I/Y。对于net income来说，N=5；PV=1；PMT=0；FV=-3；CPT I/Y。就可以求得最后的答案啦。

为什么FV是负的啊

这个正负号代表现金流入流出的方向。pv和fv的方向一定是相反的。不然就算不出答案了。

B.Net sales will grow 20% annually annet income will grow 40% annually. C.Net sales will grow 25% annually annet income will grow 50% annually. A is correct.Using the genertime value of money formulfor sales, solve for r in the equation 2 = 1 × (1+r)5. For income, solve 3 = 1 × (1+r)5. Alternatively, using a financicalculator, for sales, enter N = 5, PV = 1, PMT = 0, FV = −2 ancompute I/Y. For income, change the FV to −3 anagain solve for I/Y. The solution for sales is 14.87%; anfor income is 24.57%. fv为什么用-的？
