Answer:B
Explanation:
The weight of the water can be found by subtracting the weight of the empty bucket from the weight of the filled bucket:
Weight of water = Weight of filled bucket - Weight of empty bucket
Weight of water = 43.5 pounds - 1.8 pounds
Weight of water = 41.7 pounds
Therefore, the 5 gallons of water weigh 41.7 pounds, which is option B.
