X Company is considering replacing one of its machines in order to save operating costs. Operating costs with the current machine are $69,000 per year; operating costs with the new machine are expected to be $36,000 per year. The new machine will cost $51,000 and will last for five years, at which time it can be sold for $2,500. The current machine will also last for five more years but will not be worth anything at that time. It cost $30,000 three years ago but is currently worth only $5,000.

Assuming a discount rate of 7%, what is the incremental net present value of buying the new machine instead of keeping the current machine?

A: $71,331

B: $80,604

C: $91,082

D: $102,923

E: $116,303

F: $131,423
