3 part Multiple problem: Compute cash payback net present value and internal rate of return.1.Compute the cash payback period. Show work and give analysis for the following:Company F is considering purchasing new equipment for $300000. It isexpected that the equipment will produce annual net income of $10000 over its 10-yearuseful life. Annual depreciation will be $30000.2. Compute the net present value of each project. Show work give analysis and detail which project will be most acceptable for the following:Company D is considering two different mutually exclusive capital expenditure proposals.(a) Project A will cost $395000 has an expected useful life of 10 years a salvage value of zero and is expected to increase net annual cash flows by $70000.(b) Project B will cost $270000 has an expected useful life of 10 years a salvage value of zero and is expected to increase net annual cash flows by $50000. A discount rate of 9% is appropriate for both projects.3. Compute the approximate internal rate of return. Show work and provide written analysis for the following:DA Company is evaluating the purchase of a rebuilt spot-welding machine to be used in the manufacture of a new product. The machine will cost $170000 has an estimated useful life of 7 years a salvage value of zero and will increase net annual cash flows by $33740.
