MARR is 8%
Vidhi is investing in some rental property in Collegeville and is investigating her
income from the investment. She knows the rental revenue will increase each year, but
so will the maintenance expenses. She has been able to generate the data that follows
regarding this investment opportunity. Assume that all cash flows occur at the end of
each year and that the purchase and sale of this property are not relevant to the study.
• If Vidhi's MARR = 6% per year, is this investment a profitable undertaking? Use
Future Worth method!

Alternative A and B are two mutually exclusive cost alternatives, and one of them must be
selected. Using Incremental Analysis, which of the alternatives should be recommended based on
ERR (the External Rate of Return)? ·
MARR (Minimum acceptable rate of return) is 12% per year while the re-investment rate is
10% per year.
The study period is 20 years. Assume repeatability is appropriate for this comparison.
