Final answer:
Interest earned and notes receivable collected both increase the bank account balance, thus they are added to the bank account.
Step-by-step explanation:
The correct answer is that interest earned and notes receivable collected are added to the bank account. When a company earns interest, it represents income which increases the balance of the company's bank account. Similarly, when notes receivable are collected, this means that cash has been received, also increasing the bank account balance. It's important to recognize these transactions as positive cash flows.
