You Are Evaluating Five Investment Projects

question 4

Essay

You are evaluating five investment projects. You already calculated the rate of return for each alternative
investment and incremental rate of return between the two-paired alternatives as well. In calculating the
incremental rate of return, a lower cost investment project is subtracted from the higher cost investment project.
All rate of return figures are rounded to the nearest integers. (a) If all investment alternatives are mutually independent and the MARR is 10%,
which projects would be selected?
(b) If all investment alternatives are mutually exclusive and the MARR is 12%, which alternative should be
chosen?
(c) Suppose all investment alternatives are mutually exclusive but the MARR is 25%, which alternative should
be chosen?
