Advanced Electronics Corporation is considering purchasing a new packaging machine to replace a fully depreciated packaging machine that will last five more years. The new machine is expected to have a 5-year life and depreciation charges of $4,000 in year 1; $6,400 in year 2; $3,800 in year 3; $2,400 in both year 4 and year 5; and $1,000 in year 6. The firms estimates of revenues and expenses (excluding depreciation) for the new and old packaging machines are shown in the following table. Advanced Electronics is subject to a 40 % tax rate on ordinary income.
