Three mutually exclusive alternatives are being considered. A B C

First Cost $1,000 $2,000 $3,000
Annual benefit 150 150 0
Salvage value 1000 2700 5600
Useful life, years 5 6 7

When each project reached the end of its useful life, it would be sold for its salvage value and there wouldbe no replacement. Construct a graphical summary of the present values of these projects in order to guide a discussion of best possible options over a range of potential interest rates.
