The population of New York City is about 18.8 million people. This is about 9.9 million more people than the population of Chicago. Write and solve an equation to find the approximate population of Chicago. (1 point) • 28.7 million • 9.9 million • 9.1 million • 8.9 million
Let's assume the population of Chicago is x.
The equation that represents the given information is:
x + 9.9 million = 18.8 million.
To solve for x, we can subtract 9.9 million from both sides of the equation:
x + 9.9 million - 9.9 million = 18.8 million - 9.9 million.
This simplifies to:
x = 8.9 million.
Therefore, the approximate population of Chicago is 8.9 million.
