一道题，present value future value和investment啥的= =

you spend $1999000 dollars today, plus spend $750750 next year and spend $94815 in two years then this investment will bring benifits of $140000 every year forever with the first benifit occuring one year from today. if the firm's discount rate is 6 percent, should the firm undertake this inverstment?what rate of return does this inverstment earn?

明天要交了，万分感谢:Q

pv of perpetuity as at the end of year 0: pv = cash flow / r = 140000/0.06 = 2333333.33
npv of project using cash flow: -590381.87
don't undertake

IRR = -27.36%

19990000+750750/(1+0.06)+94815/(1+0.06)^2<140000/(1+0.06)+140000/(1+0.06)^2............+140000/(1+0.06)^n         我猜的。。

上面用discountCF来算

下面用continuing CF公式来做 做完记得在除以 1+r

上大过下不做 VICEVERSA
