Answer 1

The correct option is B The number of white wristbands is four times the number of blue wristbands.


By rounding off 192,467 to the nearest 100,000, we get 200,000.

By rounding off 789,211 to the nearest 100,000, we get 800,000.


$200,000\times 4=800,000$

This means the number of blue wristbands is four times the number of white wristbands.
