Comment on rounding

We have assumed that Marcella's account statement will report the interest rounded to 2 decimal places (cents). Hence she obtains the benefit from rounding for both months.

If there is no statement, so that rounding is not required until the end of the second month, then she may not have that extra penny in her account.
