You are deciding between two mutually exclusive investment opportunities. Both require the same initial investment of $9.9 million. Investment A will generate $2.11 million per year (starting at the end of the first year) in perpetuity. Investment B will generate $1.41 million at the end of the first year, and its revenues will grow at 2.2% per year for every year after that.

a. Which investment has the higher RR?

b. Which investment has the higher NPV when the cost of capital is 6.6%?

c. In this case, when does picking the higher IRR give the correct answer as to which investment is the best opportunity?
