Elvin Research plans to purchase a new centrifuge machine for its Washington facility. The machine costs $ 94,000 and is expected to have a useful life of 6 ?years, with a terminal disposal value of 9000. Savings in cash operating costs are expected to be $24,900 per year.? However, additional working capital is needed to keep the machine running efficiently. The working capital must continually be? replaced, so an investment of $4,000 needs to be maintained at all? times, but this investment is fully recoverable? (will be? "cashed in") at the end of the useful life. ?'s required rate of return is 12 ?%. Ignore income taxes in your analysis. Assume all cash flows occur at? year-end except for initial investment amounts. uses? straight-line depreciation for its machines.

Problem 1: Calculate net present value. ?(Use factors to three decimal? places, X.XXX, and use a minus sign or parentheses for a negative net present value. Enter the net present value of the investment rounded to the nearest whole? dollar.)

Problem 2: Calculate internal rate of return. ?(Use a? trial-and-error approach and? straight-line interpolation as necessary. Round all present value calculations to the nearest whole dollar and round the IRR to two decimal? places, X.XX%.)

Problem 3: Calculate accrual accounting rate of return based on net initial investment. ?(Round interim calculations to the nearest whole dollar. Round the final rate to two decimal? places, X.XX%.)

Problem 4: Calculate accrual accounting rate of return based on average investment. ?(Round interim calculations to the nearest whole dollar. Round the final rate to two decimal? places, X.XX%.)

Based on average investment, the accrual accounting rate of return (AARR) is

Problem 5: You have the authority to make the purchase decision. Why might you be reluctant to base your decision on the DCF? methods?
