The total amount accumulated after 3 years is \$10,544.75, and the interest earned is \$1,044.75.

Solución

Let the principal be \( P = 9500 \), the annual interest rate be \( r = 0.035 \) (i.e. \( 3.5\% \)), the number of times interest is compounded per year be \( n = 12 \) (monthly), and the time in years be \( t = 3 \). The compound interest formula is \[ A = P \left(1 + \frac{r}{n}\right)^{nt}. \] Substitute the given values into the formula: \[ A = 9500 \left(1 + \frac{0.035}{12}\right)^{12 \times 3}. \] First, compute the monthly interest rate: \[ \frac{0.035}{12} \approx 0.00291667. \] Now, calculate the total number of compounding periods: \[ 12 \times 3 = 36. \] So the formula becomes: \[ A = 9500 \left(1.00291667\right)^{36}. \] Next, calculate the value of \(\left(1.00291667\right)^{36}\). Using a calculator or exponentiation: \[ \left(1.00291667\right)^{36} \approx 1.11050. \] Multiply by the principal: \[ A \approx 9500 \times 1.11050 \approx 10544.75. \] Thus, the total amount accumulated after 3 years is \[ \$10,\!544.75. \] To find the interest earned, subtract the principal from the total accumulated amount: \[ \text{Interest Earned} = A - P \approx 10544.75 - 9500 \approx 1044.75. \] The interest earned is \[ \$1,\!044.75. \]

To find the total amount accumulated using the compound interest formula, we can use the formula: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] where: - \( A \) = the amount of money accumulated after n years, including interest. - \( P \) = principal amount (the initial amount of money). - \( r \) = annual interest rate (decimal). - \( n \) = number of times that interest is compounded per year. - \( t \) = number of years the money is invested or borrowed. For your calculation: - \( P = 9500 \) - \( r = 0.035 \) (which is \( 3.5\% \) in decimal) - \( n = 12 \) (since it's compounded monthly) - \( t = 3 \) Plugging in the values: \[ A = 9500 \left(1 + \frac{0.035}{12}\right)^{12 \times 3} \] Now calculate it step by step: 1. Calculate \( \frac{0.035}{12} \): \[ \frac{0.035}{12} \approx 0.00291667 \] 2. Now calculate \( 1 + 0.00291667 \): \[ 1 + 0.00291667 \approx 1.00291667 \] 3. Raise that to the power of \( 12 \times 3 = 36 \): \[ (1.00291667)^{36} \approx 1.109755 \] 4. Now multiply by the principal: \[ A = 9500 \times 1.109755 \approx 10545.67 \] So, the total amount accumulated after 3 years is approximately **$10,545.67**. To find the interest earned, subtract the principal from the total amount: \[ \text{Interest} = A - P = 10545.67 - 9500 \approx 1045.67 \] Thus, the interest earned is approximately **$1,045.67**.
