Answer 1

The weight of Brian's bag could be either 21.8 kg or 22.0 kg.

Step-by-step explanation:

The weight of Brian's bag is just over 21.9 kilograms. To determine which of the given options could be the weight of Brian's bag, we need to consider the rounding rules.

Since the number 21.9 is just over 21.8 and just below 22.0, the possible weights for the bag could be 21.8 kg or 22.0 kg.

Therefore, the correct options are b) 21.8 kg and c) 22.0 kg.
