Problem:
Can you please breakdown a solution as to how to solve this equation with the correct answers to each portion.
Profitability Index versus NPV. Consider these two projects:
Project      c0        c1      c2         c3
A           -$36    +$20   +$20    +$20
B            -50       +25    +20      +25
a. Which project has the higher NPV if the discount rate is 10 percent?
b. Which has the higher profitability index?
c. Which project is most attractive to a firm that can raise an unlimited amount of funds to pay for its investment projects? Which project is most attractive to a firm that is limited in the funds it can raise?
Would like a full break down of how you came up with the answer.
