Problem 11-09 Replacement Analysis The Gilbert Instrument Corporation is considering replacing the wood steamer it currently uses to shape guitar sides. The steamer has 6 years of remaining life. If kept, the steamer will have depreciation expenses of $400 for 6 years. Its current book value is $2,400, and it can be sold on an Internet auction site for $4,500 at this time. Thus, the annual depreciation expense is $2,400/6=$400 per year. If the old steamer is not replaced, it can be sold for $800 at the end of its useful life. Gilbert is considering purchasing the Side Steamer 3000 a higher-end steamer, which costs $7,800 and has an estimated useful life o 6 years with an e mated sa age alue of SaThis steam alls into the MACRS 5-years class, so the applicable depreciation rates are 20.00%, 32.00%, 19.20%, 11.52%, 11.52%, and 5.76%. The new steamer is faster and allows for an output expansion, so sales would rise by $2,000 per year; the new machine's much greater efficiency would reduce operating expenses by $1,600 per year. To support the greater sales, the new machine would require that inventories increase by $2,900, but accounts payable would simultaneously increase by $700, Gilbert's marginal federal-plus-state tax rate is 40%, and the project cost of capital is 14%. Should it replace the old steamer? The old steamer shouldbe replaced. What is the NPV of the project? Do not round intermediate calculations. Round your answer to the nearest dollar
