Final answer:
To find the amount owed at the end of four years at 3% interest compounded continuously, you can use the formula A = P * e^(rt), where A is the amount owed, P is the principal amount borrowed, e is the base of the natural logarithm, r is the interest rate, and t is the time in years. Using this formula, the amount owed at the end is approximately $4263.79.
Step-by-step explanation:
To find the amount owed at the end of four years at 3% interest compounded continuously, we can use the formula A = P * e^(rt), where A is the amount owed, P is the principal amount borrowed, e is the base of the natural logarithm, r is the interest rate, and t is the time in years. Using this formula, we have A = $3900 * e^(0.03 * 4). Plugging in the values, we find A ≈ $4263.79. Therefore, the amount owed at the end is approximately $4263.79.
