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)

Question

28.7 million

9.1 million

9.9 million

8.9 million

Answer 1

Let's assume the population of Chicago is x.

According to the problem, the population of New York City is about 9.9 million more than the population of Chicago, so we can write the equation:

x + 9.9 million = 18.8 million

To solve for x, we subtract 9.9 million from both sides of the equation:

x = 18.8 million - 9.9 million

x = 8.9 million

Therefore, the approximate population of Chicago is 8.9 million.
