A new engineer at a sand and gravel operation is considering two mutually exclusive alternatives for a small dredging system. The first option from the Diggemup Corporation would cost $122,208, have a salvage value of $14,279, and net $30,502 per year in net annual profits. The second option from the Pushmoore Mudd Group would cost $179,722, have a salvage value of $19,831, and net $34,414 per year in net annual profits.
