Answer

After 14 years, the account would have approximately \$3,400.

Solution

We use the formula for continuous compounding:   A = P × e^(rt) where   P = $2,500,   r = 0.021 (2.1% expressed as a decimal),   t = 14 years. Substitute in the values:   A = 2500 × e^(0.021×14) = 2500 × e^(0.294). Evaluating e^(0.294) gives approximately 1.3419, so   A ≈ 2500 × 1.3419 ≈ 3354.75. Rounding to the nearest hundred dollars, the balance is approximately $3,400.

Beyond the Answer

To find the amount in Sarah's account after 14 years, we use the formula for continuous compound interest: \[ A = Pe^{rt} \] where: - \( A \) is the amount of money accumulated after time \( t \), - \( P \) is the principal amount (the initial investment), - \( r \) is the annual interest rate (in decimal), - \( t \) is the time the money is invested for (in years), - \( e \) is the base of the natural logarithm (approximately 2.71828). Plugging in the values: - \( P = 2500 \) - \( r = 0.021 \) (2.1% as a decimal) - \( t = 14 \) \[ A = 2500 \times e^{0.021 \times 14} \] Calculating this: 1. Calculate \( 0.021 \times 14 = 0.294 \). 2. Find \( e^{0.294} \approx 1.3415 \). 3. Now multiply \( 2500 \times 1.3415 \approx 3353.75 \). Rounding to the nearest hundred dollars, the amount after 14 years would be approximately \( \$3,400 \).
