Brewer Vending Machine Company plans to replace $10$ of its vending machines with newer models. The current machines were purchased three years ago for $$8,000$ each and are being depreciated straight$-$line to a salvage value of $$2,000$ five years from now. The machines collectively generate annual revenue of $$30,000$ and annual expenses of $$12,000.$ The newer machines can be purchased for $$12,000$ each and would be depreciated straight$-$line to a salvage value of $$7,000$ five years from now. The new machine would generate annual sales of $$40,000$ because of less downtime than the old machines and the annual expenses of $$8,000($smaller repair bills than the old machines$).$ If Brewer's marginal tax rate is $40\%,$ what will be the incremental change in its annual cash flow if the old machines are replaced? What will be the free cash flow each period from $"0"$ to $"5"?$ Your spreadsheet should look like the following with some, or all of the items listed below.
