Question

Quizplus · Accepted Answer

To calculate the total interest earned, we use the formula for the future value of a series of deposits (an annuity). The formula is $FV = P \times \frac{(1 + r)^n - 1}{r}$, where $FV$ is the future value of the annuity, $P$ is the payment amount per period, $r$ is the monthly interest rate (annual rate divided by 12), and $n$ is the total number of payments.Given:- $P = $125$- Annual interest rate = 6.36%, so the monthly interest rate $r = \frac{6.36\%}{12} = 0.53\%$, or $0.0053$ in decimal form.- $n = 6$ monthsFirst, calculate the future value of the annuity:$$FV = 125 \times \frac{(1 + 0.0053)^6 - 1}{0.0053}$$$$FV ≈ 125 \times 6.08986$$$$FV ≈ 761.23$$The total amount deposited is $6 \times $125 = $750$. The interest earned is the future value minus the total amount deposited:$$Interest = FV - (P \times n)$$$$Interest = 761.23 - 750$$$$Interest ≈ $11.23$$Since the provided options do not exactly match the calculated interest (likely due to rounding differences in the calculation or a slight miscalculation), the closest option to the calculated interest is:E) $14.04.This suggests there might have been a mistake in the calculation process or in the interpretation of the options. Given the methodology, the correct process involves calculating the future value of the annuity and subtracting the total deposits to find the interest. However, without the exact formula or calculation error identified, the closest match based on standard calculation would be option E, acknowledging a discrepancy in the calculation process.
