2 On my 12 th birthday my grandmother gave me a choice. She handed me one silver dollar and one dime. Then, she told me that if I picked the silver dollar she would send me one more silver dollar than the year before. So for my 13 th birthday I would get 2 silver dollars. Next, she said that if I chose the dime she would send me twice as much money as the year before. So for my 13 th birthday I would get twenty cents. Which choice would have earned me the most money on my 17 th birthday?

9 You're sitting in math class, minding your own business, when in walks a success story from your school. He's made it big, and now he has a job offer for you. You'll have your choice of two payment options: 1.One cent on the first day, two cents on the second day, and double your salary every day thereafter for the thirty days; or 2.Exactly $1,000,000. (That's one million dollars!)

10 30 days is a long time and would make a VERY large table. Break the table into 1 st week, 2 nd week, 3 rd week, 4 th week, and the 29 th and 30 th day on the last table to find the pennies. That means you will have 5 tables altogether.

16 We're getting into some serious money here now, over $20,000, but still nowhere even close to a million. And there's only 10 days left. So it looks like the million dollars is the best deal. Of course, we suspected that all along.
