Q: 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?
A: 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 answer is 34.
Question: While cultivating a small farm, a farmer spent $50 on corn seeds, $35 on fertilizers and pesticides, and $15 on labor. After a successful harvest, he was able to gather 10 bags of corn. How much should he sell each bag, if he wants to make a profit of 10%?
Answer: His total expenditure so far is $50 + $35 + $15 = $100. To make a profit of 10%, he has to make a total of $100 + ($100 * (10 / 100) = $110 from sales. To make $110 from the sales of 10 bags, each bag should cost $110 / 10 = $11. The answer is 11.

Q: Roselyn gives Mara three times as many books as she gives Rebecca and remains with 60 books. If Rebecca received 40 books, how many books did Roselyn have before?
A:
If Roselyn gave Rebecca 40 books, and Mara was given three times as many books, Mara has 3 * 40 = 120 books. Rebecca and Mara's total number of books is 120 + 40 = 160 books. If Roselyn gave Mara and Rebecca her books, which is 160, then she initially had 60 + 160 = 220 books. The answer is 220.
