Final answer:
The average daily balance is $1,285.67.
Step-by-step explanation:
To find the average daily balance, we need to calculate the sum of balances for each day and divide it by the total number of days.
First, we calculate the sum of balances for the first period: $200 x 14 days = $2,800.
Next, we calculate the remaining balance after the payment: $2,800 - $45 = $2,755.
Then, we calculate the sum of balances for the second period: $2,755 x 14 days = $38,570.
Finally, we divide the total sum of balances by the total number of days: $38,570 / 30 days = $1,285.67.
Therefore, the average daily balance is $1,285.67.
