16. After opening an ancient bottle you find on the beach, a Djinni appears. In payment for his freedom, he gives you a choice of either 50,000 gold coins or one magical gold coin. The magic coin will turn into two gold coins on the first day. The two coins will turn into four coins total at the end of two days. By the end or the third day there will be eight gold coins total. The Djinni explains that the magic coins will continue this pattern of doubling each day for one moon cycle, 28 days.
Write an exponential expression that you could use to determine how many coins you would have at the end of 28 days if you chose the magical coin?
2 to the power of 28
(Sorry, I don't know how to make the exponent sign in this program. Don't judge.)
