11. Ben's Logging Company is considering replacing its old logging machine with a new, more efficient ma- chine. The old machine still works, but NOT very fast, and it will last for at least 20 more years. The new machine costs Rs. 10,000 and is expected to save the company Rs. 1,900 a year in direct costs as com- pared to the old machine. The new machine has a 10-year life with zero salvage value. Ben can borrow money at 10%, but Ben will not borrow for this new machine. Ben requires a return rate of at least 20% before taxes on these types of investments. (To make it simple, disregard taxes.) Should Ben replace the old machine?
