Bob won a lottery and was given the following choices. He could either take $8,000 at the end of each month for 30 years, or a lump sum of $1,880,000 today. Assuming weekly compounding, at approximately what interest rate (per year) would he be indifferent between the two choices? (show your calculations - suggestion you can use a financial calculator to solve this problem, and make sure to show input used for each calculator keystroke)
