To find the combined population of North and South America in 2007, we simply need to add the two populations together.
The population of North America is approximately:
\(5.15 \times 10^8\) people
The population of South America is approximately:
\(3.04 \times 10^8\) people
Now let's add these two quantities together:
\[
5.15 \times 10^8 + 3.04 \times 10^8 = (5.15 + 3.04) \times 10^8 = 8.19 \times 10^8
\]
Thus, the combined population of North and South America in 2007 is approximately:
\[
8.19 \times 10^8 \text{ people}
\]
The correct answer is:
**C 8.19 * 10 ^ 8 people**.
