Final answer:
By summing Stella's deposits and subtracting her withdrawal from the total, and then adding this to her initial balance, it is calculated that Stella's ending account balance for the month was $332.17.
Step-by-step explanation:
To find Stella's account balance at the end of the month, we need to add all the deposits to her initial balance and subtract the withdrawal. First, let's calculate the total amount deposited:
- $34.71
- $100.08
- $111.62
- $92.93
Adding these deposits together we get:
$34.71 + $100.08 + $111.62 + $92.93 = $339.34
Next, subtract the withdrawal of $27.27 from the total deposits:
$339.34 - $27.27 = $312.07
Now, add this amount to the starting balance of $20.10 to find the final balance:
$20.10 + $312.07 = $332.17
Therefore, Stella's account balance at the end of the month was $332.17.
