Final answer:
The doubling time of a quantity growing at a continuous rate of 15% per year is approximately 4.622 years.
Step-by-step explanation:
To find the doubling time of a quantity growing at a continuous rate of 15% per year, we can use the formula:
Doubling time = ln(2) / (growth rate)
Plugging in the given growth rate of 15%, the doubling time would be:
Doubling time = ln(2) / (0.15) ≈ 4.622 years
