X Company is considering replacing one of its machines in order to save operating costs. Operating costs with the current machine are $63,000 per year; operating costs with the new machine are expected to be $44,000 per year. The new machine will cost $70,000 and will last for 6 years, at which time it can be sold for $4,500. The current machine will also last for 6 more years but will have zero salvage value. Its current disposal value is $4,000. Assuming a discount rate of 5%, what is the net present value of replacing the current machine? [Note: For the capital budgeting questions, use the Present Value tables in the Coursepack or with the link after the last exam question.] A: $17,306 B: $21,633 C: $27,041 D: $33,801 E: $42,251 F: $52,814
