Answer each independent question, (a) through (e) below. a. Project A costs $6,000 and will generate annual after-tax net cash inflows of $2,650 for 5 years. What is the payback period for this investment under the assumption that the cash inflows occur evenly throughout the year? (Round your answer to 2 decimal places.) b. Project B costs $6,000 and will generate after-tax cash inflows of $850 in year 1, $1,450 in year 2, $2,500 in year 3, $2,750 in year 4, and $2,500 in year 5. What is the payback period (in years) for this investment assuming that the cash inflows occur evenly throughout the year? (Round your answer to 2 decimal places.) c. Project C costs $6,000 and will generate net cash inflows of $2,750 before taxes for 5 years. The firm uses straight-line depreciation with no salvage value and is subject to a 30% tax rate. What is the payback period under the assumption that all cash inflows occur evenly throughout the year? (Round your answer to 2 decimal places.) d. Project D costs $6,000 and will generate sales of $4,500 each year for 5 years. The cash expenditures will be $1,750 per year. The firm uses straight-line depreciation with an estimated salvage value of $750 and has a tax rate of 30%. (1) What is the accounting (book) rate of return based on the original investment? (Round your answer to 2 decimal places.) (2) What is the book rate of return based on the average book value? (Round your answer to 2 decimal places.) Use the built-in NPV function in Excel to calculate the amounts for proiects a through d. (Round your answers to the nearest whole dollar amount.) el. What is the NPV of project A?
