Answer

Explanation:

Step1: Recall mean formula

The formula for the mean (average) of a set of data is $\text{Mean}=\frac{\text{Sum of data values}}{\text{Number of data values}}$.

Step2: Identify sum and count

The sum of the daily - ending balances (total balance) is $$805$, and the number of days (number of data values) is $7$.

Step3: Calculate the mean

$\text{Mean}=\frac{805}{7}=115$

Answer:

$$115$
