Jimbob Co Jimbob Co Uses a 10% Discount Rate and the Incremental Cost

Reference: 10-13
Jimbob Co. is considering two alternatives to replace some existing manufacturing equipment. The following data have been gathered concerning these two alternatives: $$\begin{array} { | l | l | l | } \hline & \text { Machine A } & \text { Machine B } \\\hline \text { Purchase cost new } & \$ 300,000 & \$ 300,000 \\\hline \text { Overhaul costs needed year 4 } & \$ 10,000 & 20,000 \\\hline \text { Annual cash operating costs } & \$ 130,000 & \$ 120,000 \\\hline \text { Salvage value at the end of 8 years } & \$ 20,000 & \$ 30,000 \\\hline\end{array}$$ Jimbob Co. uses a 10% discount rate and the incremental cost approach to capital budgeting analysis. Both alternatives are expected to have a useful life of eight years.
-Denny Corporation is considering replacing a technologically obsolete machine with a new state-of-the-art numerically controlled machine. The new machine would cost $450,000 and would have a ten-year useful life. Unfortunately, the new machine would have no salvage value. The new machine would cost $20,000 per year to operate and maintain, but would save $100,000 per year in labour and other costs. The old machine can be sold now for scrap for $50,000. The simple rate of return on the new machine is closest to:

A) 20.00%.
B) 22.22%.
C) 8.75%.
D) 7.78%.
