user: Frank and his wife Maria have two bank accounts: savings and checking. Their savings account was empty, but early in January, Frank sold their old car for 5,000 and deposited the money in their savings account. In February, Maria realized that they owe a lot of taxes. She logged into their online bank platform and transferred the 5,000 from their savings account to their checking account. Unfortunately, she forgot to tell Frank that she did that. Frank, who does not have access to online banking, is unable to check the status of the accounts. A few days later, Frank goes to the bank to withdraw the money from the sale of their old car. Where is the money they acquired after selling the car?

assistant: The proceeds from selling their old car are in their checking account. Frank, unaware of the transfer Maria made, was surprised when the bank teller informed him that their savings account was empty. He had expected to find the $5,000 from the sale of their old car in the savings account. The bank teller, seeing his confusion, explained that the money had been transferred to their checking account. Frank, relieved to know the money was not.
