Answer:
which one of two machines to acquire given equal machine lives but unequal machine costs.
Explanation:
equivalent annual cost (EAC) is used in determining which investment to make when the investments have different life spans.
When investments have different life spans, the net present value(NPV) Â cannot be used in making decisions on investment.
EAC= [tex]\frac{rNPV}{1-\frac{1}{(1+r)^n} }[/tex]
where r = interest rate
n = number of years
The decision rule is to invest in the investment with the higher EAC
