before depreciation from $$27,000$ to $$54,000$ per year. The new machine will cost $$80,000,$ and it will have an estimated life of $8$ years

and no salvage value. The new riveting machine is eligible for $100\%$ bonus depreciation at the time of purchase. The applicable corporate

tax rate is $25\%,$ and the firm's WACC is $16\%.$ The old machine has been fully depreciated and has no salvage value.
