An industrial coal-fired boiler for process steam is
equipped with a 10-year-old electrostatic precipitator
(ESP). Changes in coal quality have caused stack
emissions to be in noncompliance with federal
standards for particulates. Two mutually exclusive
alternatives have been proposed to rectify this problem
(doing nothing is not an option). The MARR is 9% per
year. Make a recommendation regarding which
alternative to select.

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
