Answer

After 40 years, your salary would be approximately \$91,751.

Solution

To determine your salary after 40 years with a continuous annual growth rate of \(2\%\), we can use the formula for continuous compounding: \[ A = P \times e^{rt} \] Where: - \(A\) is the amount of money accumulated after time \(t\), - \(P\) is the principal amount (initial salary), - \(r\) is the annual interest rate (growth rate), - \(t\) is the time the money is invested for, - \(e\) is the base of the natural logarithm (approximately \(2.71828\)). **Given:** - Starting salary, \(P = \$41,600\) - Annual growth rate, \(r = 0.02\) (2%) - Time, \(t = 40\) years **Plugging in the values:** \[ A = 41,600 \times e^{0.02 \times 40} = 41,600 \times e^{0.8} \] First, calculate \(e^{0.8}\): \[ e^{0.8} \approx 2.22554 \] Now, multiply this by the starting salary: \[ A \approx 41,600 \times 2.22554 \approx 91,750.50 \] **Final Answer:** After 40 years, your salary would be approximately **\$91,751**.

Beyond the Answer

To determine your salary after 40 years with continuous compounding, you can use the formula for continuous growth, which is \( A = Pe^{rt} \), where \( P \) is the initial amount (starting salary), \( r \) is the growth rate, and \( t \) is the time in years. For this case: - \( P = 41,600 \) - \( r = 0.02 \) - \( t = 40 \) Now, plug in the values: \[ A = 41,600 \times e^{0.02 \times 40} \] \[ A = 41,600 \times e^{0.8} \] Using a calculator, \( e^{0.8} \approx 2.22554 \). Now, calculating the final salary: \[ A \approx 41,600 \times 2.22554 \approx 92,638.62 \] So, after 40 years with the company, your salary would approximately be \( \$ 92,638.62 \).
