please help. I'm so confused

Intro Due to high demand for wood, San Lorenzo Lumber is considering buying a new timber cutting machine to add to its existing stock. - The machine will cost $360,000 to purchase and $20,000 for shipping and installation. Last year, the firm cleared an unused area in its timber mill to make space for the machine, at a cost of $8,000. - The new cutting machine will allow the company to sell an additional 140,000 pieces of wood per year, at a price of $3 per piece. Variable costs, including timber, electricity and labor, are expected to add up to 60% of sales. - To make best use of the new machine, the company will need to increase its inventory of timber logs by $25,000. Since the firm uses trade credit when purchasing raw timber, accounts payable will increase by $12,000. - The cutting machine is expected to last 4 years and will then be sold for $35,000. It falls into the 3-year MACRS class, with depreciation rates as follows: The firm has a marginal tax rate (federal and state) of 34%. Part 1 Attempt 2/5 for 10 pts. What is the initial (year-0) project cash flow? Choose the right sign. Correct At the beginning of the project, EBIT and depreciation are both zero. Initial capital expenditure is the cost of purchase and installation: CAPEX0=360,000+20,000=380,000 This is the amount that can be depreciated over time. The cost of clearing the space for the machine is a sunk cost and should not be considered anymore. The required inventory of wood creates a positive change in net operating working capital, while the increase in accounts payable decreases net operating working capital: NOWC = Inventory Accounts payable =25,00012,000=13,000 PCF0=NOPAT+DEPCAPEXNOWC=EBIT(1t)+Dep.CAPEXNOWC=0+0380,00013,000=393,000 Part 2 Attempt 2/5 for 10 pts.
