Write and solve an equation to find the approximate population of Chicago.(1 point)%0D%0AResponses%0D%0A%0D%0A9.1 million%0D%0A9.1 million%0D%0A%0D%0A28.7 million%0D%0A28.7 million%0D%0A%0D%0A9.9 million%0D%0A9.9 million%0D%0A%0D%0A8.9 million
Let's assume the population of Chicago is "x".
According to the information given, we know that the population of New York City is 9.9 million people more than the population of Chicago:
18.8 million = x + 9.9 million
To find the population of Chicago, we need to isolate the variable "x" on one side of the equation.
Subtracting 9.9 million from both sides:
18.8 million - 9.9 million = x
8.9 million = x
Therefore, the approximate population of Chicago is 8.9 million.
