$217.98.
First, add the beginning balance of $98 to each of the deposits ($34.98, $51.02, $51.22) to get $235.22.
Next, subtract each of the withdrawals ($3.23, $4.22, $9.79) from this total to get the ending balance of $217.98.
Here, it's important to understand which amounts are withdrawals and which are deposits. Classifying the amounts correctly will tell you to subtract withdrawals and add deposits to the beginning balance. This ending balance will become your beginning balance for the next month.
