Consider four mutually exclusive altematives, each having an $8-$year useful life:

$\backslash$table$[[,$A$,$B$,$C$,$D$],[$Fist cost$,1000,800,600,500],[$Uniform Annual Benefit,$125,120,97,122],[$Salvage value,$750,500,250,0]]$

Solution:

Rank of alternatives:

$2$ Perform the IRR analysis, yields the following table FYI:
