Hi I need the anwer to this question , not similar. and also the whole answer.thank you

Answer each independent question, (a) through (e), below. a. Project A costs $8,000 and will generate annual after-tax net cash inflows of $3,250 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 $8,000 and will generate after-tax cash inflows of $1,250 in year 1, $1,950 in year 2, $3,400 in year 3, $2,950 in year 4, and $3,400 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 $8,000 and will generate net cash inflows of $3,750 before taxes for 5 years. The firm uses straight-line depreciation with no salvage value and is subject to a 20% 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.) Ed. Project D costs $8,000 and will generate sales of $4.900 each year for 5 years. The cash expenditures will be $1,950 per year. The firm uses straight-line depreciation with an estimated salvage value of $500 and has a tax rate of 20%. (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 projects a through d. (Round your answers to the nearest whole dollar amount.) e1. What is the NPV of project A? Assume that the firm requires a minimum after-tax return of 7% on investment. e2. What is the NPV of project B? Assume that the firm requires a minimum after-tax return of 7% on investment. e3. What is the NPV of project C? Assume that the firm requires a minimum after-tax return of 7% on investment. e4. What is the NPV of project D?
