Question: Four days ago, Carlos bought a bag of gummy worms. Every day he ate half of the remaining gummy worms. After eating half of the remainder on the fourth day, he now has 4 gummy worms left. How many gummy worms were in the bag when Carlos bought it?
Answer: Let G be the number of gummy worms in the bag when Carlos bought it. On the first day, he ate half the gummy worms, so he had G / 2 gummy worms. On the second day, he ate half of the remaining gummy worms, so he had G / 2 / 2 = G / 4 gummy worms. On the third day, he ate another half, so he had G / 4 / 2 = G / 8 gummy worms. On the fourth day, he ate another half and had 4 left, so he had G / 8 / 2 = G / 16 = 4 gummy worms. Thus, there were G = 4 * 16 = 64 gummy worms in the bag when Carlos bought it. The answer is 64.

Question: Mary, Edna, and Lucy are athletes who train every Saturday. Mary ran 3/8 of a 24-kilometer field on one Saturday. Edna ran 2/3 of the distance of Edna, and Lucy ran 5/6 of the distance of Edna. How many more kilometers should Lucy run to cover the same distance as Mary?
Answer: Mary ran 3 / 8 x 24 = 9 kilometers. Edna ran 2 / 3 x 9 = 6 kilometers. Lucy ran 5 / 6 x 6 = 5 kilometers. Lucy should run 9 - 5 = 4 kilometers more. The answer is 4.

Question: Aubrey is planting tomatoes and cucumbers in her garden. For each row of tomato plants, she is planting 2 rows of cucumbers. She has enough room for 15 rows of plants in total. There is enough space for 8 tomato plants in each row. If each plant produces 3 tomatoes, how many tomatoes will she have in total?
Answer:
Since one out of every 3 rows will contain tomato plants, there will be 15 / 3 = 5 rows of tomato plants. This gives her enough room to plant 5 rows * 8 plants / row = 40 tomato plants. The plants will produce a total of 40 * 3 = 120 tomatoes. The answer is 120.
