Evie's beginning balance in her checkbook was $623.65. She made deposits

of $225, wrote checks for $168.75, and had to pay a bank charge of
$3.50. What was her ending balance for the month?

First, we need to add up the deposits and subtract the checks and bank charge:

$623.65 + $225 - $168.75 - $3.50 = $676.40

Evie's ending balance for the month is $676.40.
