A corporation is considering purchasing a machine that will save$$ $$150,000$ per year before taxes. The cost of operating the machine$($including maintenance$)$ is$$ $$30,000$ per year. The machine will be needed for five$$ years, after which it will have a zero salvage value. MACRS depreciation will be$$ used, assuming a$$ three$-$year class life. The marginal income tax rate is$25\%.$ If the firm wants$15\%$ return on investment after$$ taxes, how much can it afford to pay for this$$ machine?
