The Railway Corporation has an overhead crane that has an estimated remaining life of 9 years. The crane can be sold now for $11000. If the crane is kept in service, it must be overhauled immediately at a cost of $5000. Operating and maintenance costs will be $4000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 9-year study period. A new crane will cost $21000, will last for 9 years, and will have a $8000 MV at that time.
