You are evaluating the proposed acquisition of a new machine costing $$66,000,$ and it falls into the MACRS $3-$year class. Purchase of the machine would require an increase of net operating working capital of $$4,000,$ which will be recovered when the machine is sold. The machine would increase the firm's revenues by $$26,000$ per year and its operating costs by $$12,000$ per year. The machine is expected to be used only for $3$ years and then be sold for $$25,000.$ The firm's marginal tax rate is $27$ percent, and the project's cost of capital is $14$ percent. What is the net cash flow at $t=0,$ i$.$e$.,$ the initial cash flow?
