• B. 9072000
• C. 9072
• D. 90720

Answer 1

Answer: (A)

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 $=$ $0.36\times 315=113.4$ million.

Next, we can calculate how many of those passport-holders travel internationally each year: $8\%$ of $113.4$ million $=$ $0.08\times 113.4=9072$ million.

Finally, we can calculate how many of those international travelers visit Europe each year: $10\%$ of $9.072$ million $=$ $0.01\times 9072=0.9072$ million.

$0.9072$ million is equivalent to $907,200$, which is (C).
