Question

Park County, Wyoming, has a population of approximately 28,205 people. There are two main cities in Park County: Cody, with a population of about 9,194 people, and Powell, with a population of about 5,476 people. How many residents of Park County live outside these two cities?

Answer 1

The number of the people living outside these two cities is the difference between the total population and those that live in the two cities mention. That is,
P (outside Cody and Powell) = 28205 - (9194 + 5476) = 13535
Thus, 13,535 people lived in Park Country but outside of Cody and Powell.
