Part A

There is an opportunity to expand the existing business by purchasing a new machinery for production. The machinery costs $500,000 and will be depreciated on straight-line basis to zero over 5 years. If the machinery will increase the operating profit before depreciation by $150,000, $160,000, $170,000, $180,000, and $200,000 over these 5 years. What is the average accounting rate of return for the new machinery? Assume the machine is purchased with all equity and the tax rate is 30%.


Part B

There are two mutually exclusive investment opportunities. The initial investment for both projects are $100,000. The first investment will generate $20,000 per year in perpetuity. The second project is expected to generate $15,000 for the first year and the amount will grow at 2% per year after that. The first cash flow for both investments start at the end of the first year.
