Answer: Add $45 to the book balance
Step-by-step explanation:
This is a case of bank reconciliation. Bank reconciliation occurs when the account of the bank and the company or Business are compared in order to check the differences which are then reconciled.
In this case, since the check written and paid by the bank is $649 while in the company's book, it's written as $694, then a book balance of $45 is added which is the difference between $694 and $649
