Jaime sells a bond to the Iron Bank of Braavos for 17,000 golden crowns at an interest rate of 20%. Fifteen years later, the bank demands repayment in full. Since Jaime has never paid any interest,

Jaime owes 68,000 golden crowns. This can be calculated using the formula for compound interest: A = P(1 + r/n)^(n*t) where A is the final amount, P is the initial principal, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, P = 17,000, r = 0.20, n = 1 (compounded annually), and t = 15. Plugging in the values, we get: A = 17,000(1 + 0.20/1)^(1*15) A = 17,000(1.20)^15 A = 68,024.07 Since we're dealing with a currency system that uses golden crowns, we round down to 68,000 golden crowns. Therefore, Jaime owes 68,000 golden crowns to the Iron Bank of Braavos.
