1. Diagram C 2. x represents the amount of apples in each bag 3. I would do it by adding: 28 + 4 Because: If Lin bought 4 bags of apples that each have the same amount inside, and after she ate one apple from each bag there were 28 apples left in total then: 28 + 4 = 32 (the total amount of apples she had at the beginning). To find how many apples she had in each bag (which would be the value of x): 32/4 = 8 x = 8 Lin bought 4 bags of apples with 8 apples in each bag.
