Consider a $10,000 machine that will reduce pretax operating costs by $3,000 per year over a 5-year period. Assume no changes in net working capital and a zero scrap value after five years. For simplicity, assume straight-line depreciation to zero, a marginal tax rate of 34 percent, and a required return of 10 percent. The net present value of acquiring this machine is: Group of answer choices $83. $449. $689. $827. $1,235. Flag question: Question 10 Question 10 1 pts Given the following information and assuming straight-line depreciation to zero, what is the payback period for this project? The project requires an initial investment of $900,000; has a life of 6 years; produces cost savings of $190,000 per year; has a tax rate of 35 percent; and a discount rate of 9 percent. The fixed assets will be sold for $50,000 at the end of year 6. Group of answer choices 2.54 years 3.67 years 3.93 years 5.10 years The project never pays back
