The average daily balance is the mean of the balance in an account at the end of each day in a month. The following table gives the dates and amounts of the transactions in Elliott's account in June.
There are 30 days in June.
What is the average daily balance of Elliott's account for the month of June?
I know the answer is 1583.90 dollars but why is it 9 days with that balance for day 22 if there are 30 days in June :)??
