$$ The new equipment will have a cost of $$9,000,000,$ and it is eligible for $100\%$ bonus depreciation so it will be fully depreciated at t $=0.$

$$ The old machine was purchased before the new tax law, so it is being depreciated on a straight$-$line basis. It has a book value of $$200,000($at year $0)$ and four more years of depreciation left $($$$50,000$ per year$).$

$$ The new equipment will have a salvage value of $$0$ at the end of the project's life $($year $6).$ The old machine has a current salvage value $($at year $0)$ of $$300,000.$

$$ Replacing the old machine will require an investment in net operating working capital $($NOWC$)$ of $$30,000$ that will be recovered at the end of the project's life $($year $6).$

$$ The new machine is more efficient, so the firm$$s incremental earnings before interest and taxes $($EBIT$)$ will increase by a total of $$400,000$ in each of the next six years $($years $16).$ Hint: This value represents the difference between the revenues and operating costs $($including depreciation expense$)$ generated using the new equipment and that earned using the old equipment.

$$ The project's cost of capital is $13\%.$

$$ The company's annual tax rate is $25\%.$
