Gilbert is considering purchasing the Side Steamer 3000 which cost $12,000 and has an estimated useful life of 6 years with an estimate salvage value of $1,500. This steamer falls into the NARC 5-year class with rates as 20.00%, 32.00%, 19.20%, 11.52%, 11.52% and 5.76%. The new steamer sales will raise by $2,000 per year; the new would reduce operating expenses by $1,900 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 tax rate is 40% and its WACC is 15%. Should it replace the old steamer?
