Question: Ava collects 4 more than twice as many sea shells as Ben. Ben collects 1 fewer than half as many as Carla. Carla collects 200 sea shells. How many sea shells does Ava collect?
Answer: 202 sea shells
Solution: Since Carla collects 200, Ben must collect 99 because half of 200 is 100 and one less than that is 99. Ava collects 4 more than twice as many as Ben. Twice as many as 99 is 198, and 4 more than that makes 202 sea shells.
