Alger Corp wants to buy some construction equipment for $50,000, which has a useful life of 4 years with no salvage value. Alger uses straight-line depreciation. Alger has a tax rate of 30%, and it uses a discount rate of 10%. The equipment will generate pretax income of $16,000 for the first year, but this figure will decline by 5% annually for the remaining three years. Should Alger buy this machine?
