Write and solve an equation to find the approximate population of Chicago.(1 point) Responses 28.7 million 28.7 million 9.1 million 9.1 million 9.9 million 9.9 million 8.9 million

Answer 1

Let \( C \) represent the population of Chicago. According to the information given:

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

To find the population of Chicago, we can rearrange the equation:

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

Now we can perform the subtraction:

\[ C = 18.8 - 9.9 = 8.9 \text{ million} \]

Thus, the approximate population of Chicago is 8.9 million.
