Solution
The correct answer is A. The population of the United States was approximately fifteen times the population of Australia.
Here's the step-by-step solution:
- The population of the United States in 2008 was approximately 3 × 10^8 people.
- The population of Australia in 2008 was approximately 2 × 10^7 people.
- To find out how many times larger the population of the United States was compared to Australia, we divide the population of the United States by the population of Australia.
- So, (3 × 10^8) / (2 × 10^7) = 15
- Therefore, the population of the United States was approximately fifteen times the population of Australia.
