P$9-15-$The Chaplinsky Publishing Company is considering two mutually exclusive expansion plans. Plan A calls for the expenditure of $$40$ million on a large$-$scale, integrated plant that will provide an expected cash flow stream of $$6\mathrm{.}4$ million per year for $20$ years. Plan B calls for the expenditure of $$12$ million to build a somewhat less efficient, more labor$-$intensive plant that has an expected cash flow stream of $$2\mathrm{.}72$ million per year for $20$ years. Chaplinsky's required rate of return is $10$ percent.
