Answer:
$135.84
Explanation:
Your starting checkbook balance is $134.56.
Deposits increase your balance. Add your deposit to the balance: $134.56+$345.12 = $479.68
Now add up all the checks:
$32.19+$250.00+$16.65+$45.00 = $343.84
Checks are money taken out of your account, so you subtract them from your balance
$479.68 - $343.84 = $135.84
