Bank A: Overdraft fee is $0 (if linked) or $40 (if not linked).
Bank B: Overdraft fee is $35.
Bank C: Overdraft fee is $25.
Bank D: Overdraft fee is $25. The highest possible overdraft fee is $\boxed{40}.
Explanation
Analyze the problem We need to determine which bank has the highest possible overdraft fee based on the provided table. Let's analyze the overdraft fees for each bank.
Identify overdraft fees for each bank Bank A has an overdraft fee of $0 if linked with a savings account, or $40 per overdraft if not linked. Bank B has an overdraft fee of $35 per overdraft. Bank C has an overdraft fee of $25 per overdraft. Bank D has an overdraft fee of $25 per overdraft.
Compare the overdraft fees Comparing the overdraft fees, Bank A has the potential for the highest overdraft fee at $40, provided it is not linked to a savings account. Bank B has a $35 overdraft fee, while Banks C and D both have $25 overdraft fees.
Determine the bank with the highest overdraft fee Therefore, Bank A has the highest possible overdraft fee.
Final Answer The bank with the highest possible overdraft fee is Bank A.
Examples
Understanding overdraft fees is crucial in personal finance. For example, if you accidentally overspend on your debit card, knowing which bank has the lowest overdraft fee can save you money. This is similar to comparing prices at different stores to get the best deal. By understanding these fees, you can make informed decisions about which bank to choose and how to manage your account to avoid unnecessary charges. This knowledge helps you manage your finances effectively and avoid costly mistakes.
