Answer the following question.
James and Ali together own $250. If you know that James owns $40 more than Ali, then calculate the amount owned by James.
Step-by-step reasoning process: Let X be the amount owned by James. The amount owned by Ali is X - $40. The total amount owned by both of them X + (X - $40) = $250. Combining like terms, we get X * 2 - $40 = $250. Adding $40 to both sides, we get X * 2 = $290. Dividing both sides by 2, we get X = $145.
The answer is 145.

Answer the following question.
Greg bought a 20-pack of granola bars to eat at lunch for the week. He set aside one for each day of the week, traded three of the remaining bars to his friend Pete for a soda, and gave the rest to his two sisters. How many did each sister get when they split them evenly?
Step-by-step reasoning process: Greg kept 1 granola bar for each of the 7 days of the week, so there were 20 - 7 = 13 bars left. He traded 3 to his friend Pete, so there were 13 - 3 = 10 bars left. His 2 sisters split the rest evenly, so each got 10 / 2 = 5 granola bars.
The answer is 5.

Sami finds 3 spiders in the playground. Hunter sees 12 ants climbing the wall. Ming discovers 8 ladybugs in the sandbox, and watches 2 of them fly away. How many insects are remaining in the playground?
Step-by-step reasoning process: The children find 3 + 12 + 8 = 23 insects. After the ladybugs fly away, there are 23 - 2 = 21 insects.

Answer the following question.
A park is 1000 feet long and 2000 feet wide. If there is 1 tree per 20 square feet, how many trees are there in the park?
Step-by-step reasoning process: The park is 2,000,000 square feet because 1000 * 2000 = 2,000,000. Thus, there are 100,000 trees in the park because 2,000,000 / 20 = 100,000.
The answer is 100000.
