How Many Tourists Visited Italy in 2000?

[Rasalhague]

Homework Statement

Some tourists return to the same country several times in the same year. In 2000, it was noted that 80% of tourists made a single trip to the country, 15% came twice, and 5% came at least three times. How many individual tourists visited Italy in 2000.

(Table shows "Tourists statying at least one night when visiting Italy": 22 800 000.)

Homework Equations

The Attempt at a Solution

x = 22800000/(.8+2*.15+3*.05) = 18 240 000.

So I'd say there were up to 18 240 000 individual tourists. But the question, a multiple choice question, doesn't have anything close to this option. Am I overlooking something, or misinterpreting it? Could there be a typo?

Are you missing some information? How long is a once-a-year trip, on average? For example, last year I visited London just once, but stayed 7 nights.

That's all the information I have. It's a sample numeracy test question. It came in a list of them, and the others seem pretty straightforward, not brain-teasers, just testing basic skills.
