Let's consider the problem that is the continuous-time analog to the above discrete-time problem. This is perhaps a more realistic problem. Suppose interest is compounded continuously instead of discretely. You may again choose how many years to hold the case of wine before selling it - but now suppose you can sell at any time, not just at the integer years. How many years should you hold the case of wine before selling it? How much money will you receive for the case of wine at the time of its sale
