You currently have $2,700 (Present Value) in an account that has an interest rate of 4.5% per year compounded continuously. You want to withdraw all your money when it reaches $5,130 (Future Value). In how many years will you be able to withdraw all your money? The number of years is . Round your answer to 1 decimal place.
Question
Answer:
To find the number of years it will take for the account balance to reach $5,130, we can use the formula for continuous compound interest:
FV = PV * e^(rt)
where FV is the future value, PV is the present value, e is Euler's number (approximately 2.71828), r is the interest rate, and t is the time in years.
Plugging in the given values, we have:
5130 = 2700 * e^(0.045t)
To solve for t, we can divide both sides by 2700:
5130/2700 = e^(0.045t)
Taking the natural logarithm (ln) of both sides to isolate the exponent, we get:
ln(5130/2700) = 0.045t
Simplifying this equation:
ln(1.9) = 0.045t
Using a calculator to evaluate the natural logarithm of 1.9, we find:
0.64185388617 = 0.045t
Now, we can solve for t by dividing both sides by 0.045:
t = 0.64185388617 / 0.045 β 14.3
Therefore, it will take approximately 14.3 years to withdraw all your money. Rounding to 1 decimal place, the answer is 14.3 years.
