(1) Look for a pattern: 2c (after one day), 4c (after 2 days)...

(2) Write this as a formula: 2 to the power n after n days.

(3) Try to compute this: 2³⁶⁵ Your calculator may return an error because the number is too big. Otherwise you get about 7.5 x 10¹⁰⁹ c or $7.5x10¹⁰⁷, a number far too big to be meaningful as money.

Let's explore this. Divide by $1000 to convert approximately to ounces of gold.

7.5x10¹⁰⁴ oz

or more than 10¹⁰³ kilograms of gold.

Now look up the mass of the observable universe on the Internet.

Good Hunting!
