St$.$ Johns River Shipyards is considering the replacement of an $8-$year$-$old riveting machine with a new one that will increase earnings before depreciation from

$$30,000$ to $$44,000$ per year. The new machine will cost $$82,500,$ 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 $18\%.$ The old machine has been

fully depreciated and has no salvage value.
