Answer 1

Let's denote the population of Chicago as \( x \). According to the problem, the population of New York City is about 9.9 million more than the population of Chicago. We can write the equation as:

\[ 18.8 \text{ million} = x + 9.9 \text{ million} \]

To solve for \( x \), we subtract 9.9 million from both sides:

\[ x = 18.8 \text{ million} - 9.9 \text{ million} \]

Calculating that gives:

\[ x = 8.9 \text{ million} \]

So, the approximate population of Chicago is 8.9 million.
