PLEASE I NEED IT ASAP

Wendell's Donut Shoppe is investigating the purchase of an $34.500 donut-making machine with a six-year useful life. The new machine would reduce labor costs by $5,600 per year. In addition, it would allow the company to produce one new style of donut, resulting in the sale of 1,600 dozen more donuts each year. The company realizes a contribution margin of $200 per dozen donuts sold. Required: 1. What are the new machine's total annual cash inflows? 2 What discount factor should be used to compute the new machine's internal rate of return? Note: Round your onswer to 3 decimol ploces. 3. What is the new machine's internal rate of return? Note: Round your final onswer to the nearest whole percentage. 4. In addition to the data given previously, assume the machine will have a $15.645 salvage value at the end of six years. Under these conditions, what is the internal rate of return? (Hint: You may find it helpful to use the net present value approach, find the discount rate that will cause the net present value to be closest to zero) Note: Round your final onswer to the nearest whole percentoge
