A company is considering two mutually exclusive expansion plans, Plan A requires a $40 million expenditure on a large-scale integrated plant that would provide expected cash flows of $6.39 million per year for 20 years. Plan B requires a $15 million expenditure to bulld a somewhat less efficient, more labor Intensive plant with an expected cash flow of $3.36 million per year for 20 years. The firm's WACC IS 10%. The data has been collected in the Microsoft Excel Online file below. Open the spreadsheet and perform the required analysis to answer the questions below. Open spreadsheet a. Calculate each project's NPV. Round your answers to two decimal places. Do not round your intermediate calculations. Enter your answers in millions. For example, an answer of $10,550,000 should be entered as 10.55. Plan A: $ million Plan : million Calculate each project's IRR. Round your answer to two decimal places Plan A: Plan B b. By graphing the NPV proles for Plan A and Plan B, approximate the crossover rate to the nearest percent c. Calculate the crossover rate where the two projects NPVs are equat. Round your answer to two decimal places
