We are told that the project with highest EAA is the one that is preferred in chained unequal project life
in the answers it shows that the lowest EAA is actually the optimal one.
can anyone explain why?
I havent had time to do this EOC, but from reading the solution : they chose the one with the lowest cost.
Indeed usually you would choose the one with the highest revenue, in this case they talk about expense, so you do want the one with the lowest expense. This is tricky but logic.
