Two mutually exclusive alternatives are being considered. Both have lives of 5 years. Alternative A has a first cost of $2,500 and annual benefits of $746.

You must state here on Blackboard all rates of return (in percent to 2 decimal places, e.g.4.47% or 25.61%) you used to make the selection. SHOW YOUR REASONING/WORK
