A company is considering two mutually exclusive expansion plaris, Plan A requires a $39 million explenditure on a large-scale integrated plant that would provide expected cash flows of $6.23 million per year for 20 years. Plan B requires a $12 million expenditure to bulld a somewhat less efficient, more labor* intensive plant with an expected cash flow of $2.69 million per year for 20 years. The firm's WacC is 11%.
