Supporting Activity 2 Saving Account as a Class
Write a 200- to 300-word short-answer response to the following:
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.
