please help me answer cf5 and npv for this problem

DeYoung Entertainment Enterprises is considering replacing the latex molding machine it uses to fabricate rubber chickens with a newer, more efficient model. The old machine has a book value of $600,000 and a remaining useful life of 5 years. The current machine would be worn out and worthless in 5 years, but DeYoung can sell it now to a Halloween mask manufacturer for $270,000. The old machine is being depreciated by $120,000 per year for each year of its remaining life. The new machine has a purchase price of $1,190,000, an estimated useful life and MACRS class life of 5 years, and an estimated salvage value of $105,000. The applicable depreciation rates are 20.00%,32.00%,19.20%,11.52%,11.52%, and 5.76%. Being highly efficient, it is expected to economize on electric power usage, labor, and repair costs, and, most importantly, to reduce the number of defective chickens. In total, an annual savings of $250,000 will be realized if the new machine is installed. The company's marginal tax rate is 35% and the project cost of capital is 12%. a.

Calculate the annual depreciation allowances for both machines, and compute the change in the annual depreciation expense if the replacement is made. Do not round intermediate calculations. Round your answers to the nearest dollar. c. What are the incremental net cash flows in Years 1 through 5 ? Do not round intermediate calculations. Round your answers to the nearest dollar. d. Should the firm purchase the new machine
