Explanation:
There were approximately 200 million moviegoers in the county, and 11/20 (or 55%) of them were aged 16-23. To find the approximately number of people aged 16-23 who attended the movies in that year, we can use the formula:
approximate number of people = proportion of people in the group * total number of people
approximate number of people = 0.55 * 200 million = 110 million
Therefore, we can say that approximately 110 million people aged 16-23 attended the movies in the county in the given year.
