To find the combined population of North and South America in 2007, we can simply add the two populations together:

1. North America's population: \( 5.15 \times 10^8 \)
2. South America's population: \( 3.04 \times 10^8 \)

Adding these two values:

\[
5.15 \times 10^8 + 3.04 \times 10^8 = (5.15 + 3.04) \times 10^8
\]

Calculating the sum in the parentheses:

\[
5.15 + 3.04 = 8.19
\]

So, the combined population is:

\[
8.19 \times 10^8
\]

Thus, the combined population of North and South America in 2007 is approximately \( 8.19 \times 10^8 \) people.
