of a new tunneling X-ray microscope for $200,000. The net benefits from gains in materials engineering is projected to be $40,000 in real dollars at the end of the first year increasing by an arithmetic gradient of $10,000 per year in real dollars for the first 5 year life of the X-ray and leveling off at $80,000 per year in years 6 and 7The unit will be depreciated under MACRS. Due to increasing advances in tunneling X-ray microscope technology, the unit will have SO salvage value at the end of its 7 year life. During the year analysis period, inflation is expected to be at 40% per year. The corporation has a combined state and federal 40% income tax rate. The corporation requires a 20% after-tax market rate of return on its research and development investments. Should the X-ray unit be purchased
