The total value of Rebecca's savings account after 4 years can be calculated using the formula for compound interest. In this case, however, since her account pays a simple annual interest rate of 2.5%, we can use a simpler formula to calculate the total value.
To calculate the total value of the account after 4 years, we need to multiply the initial deposit by the interest rate and the number of years. In this case, the initial deposit is $4,280 and the interest rate is 2.5%.
To calculate the interest earned over 4 years, we can use the formula: Interest = Initial Deposit * Interest Rate * Number of Years. Plugging in the values, we get: Interest = $4,280 * 2.5% * 4 = $428.
To find the total value of the account after 4 years, we add the interest earned to the initial deposit. Therefore, the total value of the account after 4 years is: Total Value = Initial Deposit + Interest = $4,280 + $428 = $4,708.
So, the total value of Rebecca's savings account after 4 years will be $4,708.
Please note that this calculation assumes that the interest is compounded annually. If the interest were compounded more frequently (e.g., quarterly or monthly), the total value of the account would be slightly higher.
