You have won Powerball! A $$200$ Million jackpot. The lottery officials give you a choice. You can take $$10$ Million per year for $20$ years starting now $($year $0$ of $$10$ Million $+19$ additional payments over time$).$ Or take $$100$ Million today. Which is the better deal. Assume your opportunity cost $($the interest rate you could earn with the money$)$ is $6\%$ for a relatively safe investment. Which is the better deal?
