Q. Emily received a bonus of $9,000\$9,000 from her company and wants to invest it in an account to save for a dream vacation. Her investment account has a 10%10\% interest rate compounded continuously. How long will it take for her money to grow to $24,420\$24,420?? \newlineUse the formula A=PertA = Pe^{rt}, where AA is the balance (final amount), PP is the principal (starting amount), ee is the base of natural logarithms (2.71828\approx 2.71828), rr is the interest rate expressed as a decimal, and tt is the time in years. \newlineRound your answer to the nearest tenth.
  1. Identify values: Identify the values for PP, AA, rr, and tt.\newline P=9000P = 9000\newline A=24420A = 24420\newline r=0.10r = 0.10
  2. Use formula: Use the formula A=PertA = Pe^{rt}.\newline 24420=9000×e0.10×t24420 = 9000 \times e^{0.10 \times t}
  3. Divide to isolate: Divide both sides by 90009000 to isolate e0.10×te^{0.10 \times t}.\newline 244209000=e0.10×t\frac{24420}{9000} = e^{0.10 \times t}\newline 2.7133333=e0.10×t2.7133333 = e^{0.10 \times t}
  4. Take natural logarithm: Take the natural logarithm of both sides to solve for t t .\newline ln(2.7133333)=0.10t\ln(2.7133333) = 0.10 \cdot t
  5. Calculate logarithm: Calculate the natural logarithm. ln(2.7133333)0.998\ln(2.7133333) \approx 0.998\newline 0.998=0.10t0.998 = 0.10 \cdot t
  6. Solve for tt: Solve for tt by dividing both sides by 0.100.10.\newline t=0.9980.10t = \frac{0.998}{0.10}\newline t9.98t \approx 9.98
  7. Round to nearest tenth: Round to the nearest tenth.\newline t10.0t \approx 10.0\newlineSo, it will take approximately 10.0 years for Emily's money to grow.
