A company is considering investing in a new machine that costs $$100,000$ and has

a useful life of $5$ years. The machine is expected to generate incremental cash

inflows of $$30,000$ per year. The company's tax rate is $25\%.$ If the salvage value of

the machine is estimated to be $$20,000$ at the end of its useful life, what is the net

present value $($NPV$)$ of the investment? Assume a discount rate of $8\%.$
