Question 1173027
Let's calculate the average daily balance for October:

**1. Determine the Daily Balances:**

* **Oct 1-2:** Balance = $110 (2 days)
* **Oct 3-6:** Balance = $110 + $50 = $160 (4 days)
* **Oct 7-9:** Balance = $160 - $75 = $85 (3 days)
* **Oct 10-15:** Balance = $85 + $29.59 = $114.59 (6 days)
* **Oct 16-24:** Balance = $114.59 - $30 = $84.59 (9 days)
* **Oct 25-31:** Balance = $84.59 + $123.60 = $208.19 (7 days)

**2. Calculate the Sum of Daily Balances:**

* (2 * $110) + (4 * $160) + (3 * $85) + (6 * $114.59) + (9 * $84.59) + (7 * $208.19)
* $220 + $640 + $255 + $687.54 + $761.31 + $1457.33 = $4021.18

**3. Divide by the Number of Days in October (31):**

* $4021.18 / 31 = $129.71548387

**4. Round to the Nearest Cent:**

* $129.72

**Answer:**

The average daily balance is $129.72.
