The average daily balance (ADB) for deposit accounts is equal to the total of balances in a month divided by the days in that month.
In this problem
The average daily balance (ADB) of Elliot's account for the month of June is equal to the total of balances in June divided by 30 (because there are 30 days in June)

Divided by 30
ADB=$1,655/30=$55.17
