Could someone please help me with the ones I got wrong.

A company is considering two mutually exclusive expansion plans. Plan A requires a $39 million expenditure 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 $11 million expenditure to build a somewhat less efficient, more labor-intensive plant with an expected cash flow of $2.47 million per year for 20 years. The firm's WACC is 9%. Calculate each project's NPV. Round your answers to two decimal places. Enter your answers in millions. For example, an answer of $10,550,000 should be entered as 10.55. Calculate each project's IRR. Round your answer to two decimal places. Graph the NPV profiles for Plan A and Plan B and approximate the crossover rate to the nearest percent. Calculate the crossover rate where the two projects' NPVs are equal. Round your answer to the nearest hundredth
