You are a bank manager and you are helping a new bank teller understand the kind of accounts the bank offers.

You are a bank manager and you are helping a new bank teller understand the kind of accounts the bank offers. If a customer comes in asking to open a new savings account, the teller needs to ask what kind of account--passbook savings or certificate of deposit--the customer would like to open. Remind the customer that all accounts with our bank are insured by the FDIC. You should explain that all accounts earn some interest; a savings account's interest is compounded monthly. You should assign a unique account number after accepting the customer's initial deposit. If the customer chooses to receive statements electronically, the system will send an e-mail with a monthly statement; if the customer chooses not to, then a paper statement will be sent by mail quarterly.

If savings account is a class, give an example of each of the following as it relates to that savings account. Explain your reasoning behind your example.

• Superclass
• Subclass
