The machine has an original purchase price of $80,000, installation cost of $20,000, and will be depreciated under the five-year MACRS. Net working capital is expected to decline by $5,000. The firm has a 40 percent tax rate on ordinary income and long-term capital gain. The terminal cash flow is __________.
