A company is considering two mutually exclusive expansion plans. Plan A requires a $$40$ million initial outlay on a large$-$scale integrated plant that would provide expected cash flows of $$6\mathrm{.}39$ million per year for $20$ years. Plan B requires a $$12$ million initial outlay to build a somewhat less efficient, more labor$-$intensive plant with expected cash flows of $$2\mathrm{.}69$ million per year for $20$ years. The firm's WACC is $11\%.$
