Answer:
276 thousand visitors.
Explanation:
When you are rounding numbers remember that you round to the next number if the number immidiately to the right to the one you are rounding is 5 or higher, and if it is 4 or lower you round to the number you originally have, for example if you have 275,405, you round it to the nearest thousand to 274 thousand, since the immidiate next number is 4 and that rounds down. In this case the next immidiate number is 6 so you round up to 276 thousand.
