URGENT!! PLEASE HELP!!

The Ajax Corpoartion has an overhead crane that has an estimated remaining life of 9 years. The crane can be sold now for $8,000. If the crane is kept in service, it must be overhauled immidiately at a cost of $5,000. Operating and maintenance costs will be $2,000 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 $16,000, will last for 9 years, and will have a $5,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane. The company uses a before-tax interest rate of 11% per year in evaluating investment alternatives. Should the company replace the old crane?
