To find the combined population of North and South America in 2007, we will add the two populations together.
The population of North America is approximately \(5.15 \times 10^8\) and the population of South America is approximately \(3.04 \times 10^8\).
We can add these two values directly:
\[
5.15 \times 10^8 + 3.04 \times 10^8
\]
Since both populations are expressed in terms of \(10^8\), we can factor out \(10^8\):
\[
(5.15 + 3.04) \times 10^8
\]
Calculating the sum inside the parentheses:
\[
5.15 + 3.04 = 8.19
\]
Now, we can express the combined population:
\[
8.19 \times 10^8
\]
Thus, the combined population of North and South America in 2007 is approximately \(8.19 \times 10^8\) people.
