Answer:
we start with the bank balance: $9,900.50
we must add: deposits in transit $1,315.80
we must subtract: check N° 314 for $48.50 and check N° 485 for $465.12
= $9,900.50 + $,315.80 - $48.50 - $465.12 = $10,702.68
now we start with the checkbook balance: $9,512.88
we add: the note collected for $1,200
we must subtract: processing fees = $0.15 x 68 checks = $10.20
= $9,512.88 + $1,200 - $10.20 = $10,702.68
bank balance = checkbook balance
$10,702.68 = $10,702.68
