You are the new manager at a plant. Part of your job is oversight of a machine. You would like to know what the company paid for it and when they will need to replace it.
When you ask your questions of the cost accountant, he decides to give you a hard time, and says "Well, we've had the thing awhile. 7 years I'd say, and we are going to run it until its worth nothing to anybody. If I remember correctly, 5 years ago the book value was $56182 and two years ago it was $27349. So, you go figure it out.
Assuming the depreciation was linear figure out:
a) What the the company paid for the machine originally:
b) when will it be worth nothing?
