The Kuwait Oil Exploration Company is considering two mutually exclusive plans for extracting oil property for which it has mineral rights. Plan A calls for the expenditure of $1,000,000 to drill development wells and Plan B calls for the expenditure of $1,500,000. Under Plan A, cash flows will be $30,000 per year for the next 50 years. Under Plan B, cash flows will be $50,000 per year for the next 50 years. Assume that the required rate of return is 8%.

Calculate the discounted payback period for both projects.
