You just met Harry Potter and he gave you a magic coin! The coin doubles every day! On the second day, you have two coins and on the third day you have four coins. The equation for the third day is 2^2. Each coin is worth $10. How much money will you have on the 15th day? Explain how you got your answer.

You will have $163,840 on the 15th day. First, I found out how many coins you would have by solving 2^14 = 16,384. Next, I multiplied my answer by $10 by moving my decimal one place to the right, which gave me $163,840.
