X Company is considering replacing one of its machines in order to save operating costs. Operating costs with the current machine are $60,000 per year; operating costs with the new machine are expected to be $32,310 per year. The new machine will cost $154,000 and will last for four years, at which time it can be sold for $1,000. The current machine will also last for four more years but will not be worth anything at that time. It cost $44,000 four years ago, but its current disposal value is only $4,000. 9. Assuming a discount rate of 8%, what is the incremental net present value of replacing the current machine?
