You have a bond and bank account that pay 5% and 3% compounded annually. You are allowed to buy or borrow the bond (needing to repay it back later). Similarly, you are able to borrow money from the bank (needing to pay the principal and interest at the end) or deposit money into the bank. There is an arbitrage opportunity. How much profit will you receive at the end of 11 year if you have $200 total?
