To solve for the average daily balance, we need to calculate the daily balance over each period in the billing cycle and divide the total by the number of days in the cycle.

Here's how to approach it with the given dataTo solve for the average daily balance, we need to calculate the daily balance over each period in the billing cycle and divide the total by the number of days in the cycle.

Here's how to approach it with the given 

1. **List the Balance and Days**: 
   Based on the image, each transaction changes the balance, and each new balance lasts for a certain number of days.

   | Date       | Balance | Days |
   |------------|---------|------|
   | Nov 1-7    | $5,000  | 6    |
   | Nov 7-20   | $5,143  | 13   |
   | Nov 20-21  | $5,199  | 1    |
   | Nov 21-24  | $5,375  | 3    |
   | Nov 24-26  | $5,434  | 2    |
   | Nov 26-30  | $5,589  | 4    |

2. **Calculate the Balance Over Each Period**: 
   Multiply each balance by the corresponding number of days to get the balance-days.

   - Nov 1-7: $ 5,000 \times 6 = 30,000 $
   - Nov 7-20: $ 5,143 \times 13 = 66,859 $
   - Nov 20-21: $ 5,199 \times 1 = 5,199 $
   - Nov 21-24: $ 5,375 \times 3 = 16,125 $
   - Nov 24-26: $ 5,434 \times 2 = 10,868 $
   - Nov 26-30: $ 5,589 \times 4 = 22,356 $

3. **Sum the Balance-Days**: 
   Add all these values together.
   
   \[
   30,000 + 66,859 + 5,199 + 16,125 + 10,868 + 22,356 = 151,407
   \]

4. **Divide by the Total Number of Days**: 
   There are 30 days in November, so we divide the total balance-days by 30.

   \[
   \frac{151,407}{30} = 5,046.90
   \]

Therefore, the **Average Daily Balance** is **$5,046.90**.
