Question: Continue the mercury recovery example from the lecture, assuming the company plans to invest in the Quicksilver device. The Quicksilver device has an initial cost of $40,000, annual operating cost of $7,000, annual revenue from sale of recovered mercury of $2,200, and a salvage value of $8,000 at the end of its 10-year expected lifetime. Calculate the internal rate of return (IRR) for this investment. The company's minimum acceptable rate of return (MARR) is 10%. Would they choose to invest in this device if it were not required by the new environmental regulations?
