Problem 11.31

Randall-Rico Consultants, 5 years ago, pur­chased for $45,000 a microwave signal graphi­cal plotter for corrosion detection in concrete structures. It is expected to have the market val­ues and annual operating costs shown for its re­maining useful life of up to 3 years. It could be traded now at an appraised market value of $8000.

A replacement plotter with new Internet-based, digital technology costs $125,000, has an esti­mated salvage value of 8% of the purchase price after its 5-year life, and an AOC of 20% of its pur­chase price. At an interest rate of 15% per year, determine how many more years Randall-Rico should retain the present plotter.
