Three mutually exclusive alternatives are being

considered.

Each alternative has a $20-$year useful life with no

salvage value.

Construct a choice table for interest rates from $0\%$ to $100\%($With and without the

Do$-$nothing option$).$

You have to use the Incremental rate of return Analysis method. You will lose $50\%$

of points if you compare the alternatives for different interest rates.
