please solve the question and compare it with the solution that I have I want to know how my teacher got these amounts

UUPII Duubos +3 The Erickson Toy Company currently uses an injection-molding machine that was purchased 3 years ago. This machine is being depreciated on a straight-line basis toward a $5,000 salvage value, and it has 5 years of remaining life. The cost of the machine 3 years ago was $150.000. It can be sold for $25,000 at this time. New The firm is offered a replacement machine, which has a cost of $250,000 and an estimated useful life of 5 years and an estimated salvage value of $25000. The replacement machine would permit an output expansion so sales would rise by $50,000 per year, but costs would increase by $10,000 per year. The new machine would require that net working capital would increase by $10,000 initially and 10% to support incremental sales. The tax rate is 40% and the firm's COC is 10%. Should it replace the old machine? Calculate the NPV of this decision and the IRR. departe 2892- = 45. dep colo) Capital Budgeting Template Discount rate Income tax rate BV old machines Incremental Sales Salvage value old machine 10 40 15.625 50 - 5.
