Jackson’s backpack weighs 734 pounds. After he adds food and water to his backpack, it weighs 1134 pounds. If the water weighs 134 pounds, how much does the food weigh?
First, you subtract 734 from 1134 to get 400. Then, you subtract the number of pounds the water weighs from how much the food and water weighs. So you basically do 400 - 134 to get 266.
