The Banana Republic Company is considering the replacement of an old fruit picking machine with a new machine. The new machine would increase after$-$tax earnings from $$20,000$ per year to $$51,000$ per year as of year $1$ onward. The new machine will cost $$100,000$ and has an estimated life of eight years with a salvage value of $$12,000.$ The company uses straight$-$line depreciation and the new machine has an Investment Tax Credit $($i$.$e$.$ tax reimbursement$)$ of $7\%$ of its cost. Also in year $0$ the new machine will increase Accounts Receivable by $$5,000$; increase Accounts Payable by $$3,500$; and decrease Inventories by $$4,000.$ The old machine has a book value of $$48,000$ now, with a remaining useful life of $8$ years, and is being depreciated to an estimated $$8,000$ salvage value using the straight$-$line depreciation. The old machine has a current market value of $$18,000.$ It will be deactivated. The corporate tax rate is $40\%,$ and the firm$$s cost of capital is $12\%.$

What is the firm's incremental CF during operation of the new machine?
