The local police department is considering two types of sidearms for its officers. The Glock 40 costs $400 apiece and has a life of 5 years. The other option is a Sauer 45 that costs $800 and has a 10-year life. The Sauer pistol has a residual value of $200 at the end of its 10-year service life. Assume repeatability and compute the internal rate of return on the incremental cash flow of the two pistols. If the department uses aMARR of 5% per year, is the Sauer 45 the better choice?
