Verified step by step guidance

Understand the concept of an interest rate: The interest rate is the percentage at which money in a savings account grows over time. It is typically expressed annually as the Annual Percentage Rate (APR).
Identify the role of the interest rate: The interest rate directly impacts the amount of interest earned on the principal balance in the account. Higher interest rates result in more earnings over time.
Clarify the unrelated options: The number of withdrawals allowed per month, the maturity date of the account, and the initial deposit required to open the account are not determined by the interest rate. These are typically set by the bank's policies or the type of account.
Relate the interest rate to time: The interest earned is calculated based on the principal amount, the interest rate, and the time the money remains in the account. Use the formula for simple interest: , where I is interest, P is principal, R is the interest rate, and T is time.
Conclude the correct answer: The interest rate determines the amount of interest earned over time, as it directly influences the growth of the account balance.
