Your company is considering a machine that will cost $1,000 at Time 0 and which can be sold after 3 years for $100. To operate the machine, $200 must be invested at Time 0 in inventories; these funds will be recovered when the machine is retired at the end of Year 3. The machine will produce sales revenues of $900/year for 3 years; variable operating costs (excluding depreciation) will be 50 percent of sales. Operating cash inflows will begin 1 year from today (at Time 1). The machine will have depreciation expenses of $500, $300, and $200 in Years 1, 2, and 3, respectively.

Inflation is zero. What is the project's NPV? a. $7.89 b. $8.87 c. $6.24 d. $10.41 e. $9.15
