Given the stream of consciousness rationale, provide a reasonable question and answer. Rationale: Mary carried 4 + 3 = 7 buckets of sand. Iris carried 7 1 = 6 buckets of sand. All together, they carried 4 + 7 + 6 = 17 buckets of sand. The sand weighed a total of 17 * 2 = 34 pounds.
The question and answer:
Eden, Mary and Iris gather sand to fill their sandbox. Eden carried 4 buckets of sand. Mary carried 3 more buckets of sand than Eden. Iris carried 1 less bucket of sand than Mary. If each bucket contains 2 pounds of sand, how many pounds of sand did they collect in total?
The answer is 34
