9. 5.9 U.S. Steel is considering a plant expansion to produce austenitic, precipitation hardened, duplex, and martensitic stainless-steel round bars that is expected to cost $13 million now and another $10 million 1 year from now. If total operating costs will be $1.2 million per year starting 1 year from now, and the estimated salvage value of the plant is virtually zero, how much must the company make annually in years 1 through 10 to recover its investment plus a return of 15% per year?
