Anna is testing different weights of certain things. The bucket she is holding that is full of water weighs 5lbs. Anna weighs he
rself and she is 97 pounds. She then drinks all of the water out of the bucket and then weighs herself again. Now she weighs 104 pounds. If the bucket of water she held was only 5 pounds, how did Anna gain 7 pounds from drinking the water out of it? __________________________________________________
