[Question]: Bert fills out the daily crossword puzzle in the newspaper every day. He uses up a pencil to fill out the puzzles every two weeks. On average, it takes him 1050 words to use up a pencil. How many words are in each crossword puzzle on average?
[Answer]: At 7 days a week, it takes Bert 2 * 7 = 14 days of daily crossword puzzles to use up a pencil. Since Bert does one puzzle a day, each crossword puzzle has 1050 / 14 = 75 words.
So the answer is 75.

[Question]: In a math test, Mark scored twice as much as the least score. If the highest score is 98 and the range of the scores is 75, what was Mark's score?
[Answer]: The range of scores is the difference between the highest and the least score so 75 = 98 - least score. Then the least score = 98 - 75 = 23. Mark scored twice as much as the least score which is 2 * 23 = 46.
So the answer is 46.

[Question]: 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?
[Answer]:
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.
So the answer is 34.
