Final answer:

Step-by-step explanation:
To find the remaining balance in the bank manager's travel expense account, we need to calculate half of the monthly salary and subtract the expenses from it.
First, calculate half of the monthly salary: $6,260 / 2 = ${{6260/2=3130}}
Next, subtract the expenses from half of the monthly salary: $3130 - ($872 + $399 + $568) = ${{3130-(872+399+568)=1291}}
The remaining balance in the bank manager's travel the expense account for last month is $1291.
