How many pounds does the pack weigh when including the bottle?

• A. 28 lbs
• B. 29 lbs
• C. 30 lbs
• D. 31 lbs

Answer: (C)

The key idea is that the total weight of the pack equals the weight of the empty pack plus the weight of the bottle (and any attached gear that stays with the pack). To determine the total, you simply add these component weights together. In this setup, the numbers provided for the pack and the bottle add up to 30 pounds, so the pack weighs 30 pounds when the bottle is included. The other numbers would only be correct if the component weights were different, which isn’t the case here.
