• Option A requires an initial investment of $800 million and generates annual cash flows of $200 million for the next five years.
• Option B requires an initial investment of $1 billion and generates annual cash flows of $250 million for the next six years. If PepsiCo's required rate of return is 10%, which option should they choose based on the net present value method?
