Thirty-six percent of the 315 million people residing in the United States currently hold a passport. Of these passport-holding individuals, 8% travel internationally every year. Of those who travel internationally every year, approximately 10% visit European countries. How many U.S. residents visit European countries every year?
A. 9072 B. 90720 C. 907200 D. 9072000
Explanation: C Let's break this question into smaller pieces. First, to find the number of U.S. residents who visit European countries every year, we will need to determine how many residents hold passports: 36% of 315 million = 0.36 × 315 = 113.4 million. Next, we can calculate how many of those passport-holders travel internationally each year: 8% of 113.4 million = 0.08 × 113.4 = 9.072 million. Finally, we can calculate how many of those international travelers visit Europe each year: 10% of 9.072 million = 0.1 × 9.072 = 0.9072 million. 0.9072 million is equivalent to 907,200, which is (C). The percentage calculations can also be done in one step: 0.1 × 0.08 × 0.36 × 315 = 0.9072 million.
