[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?
[Answer]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.
Q: Jason has six fish in his aquarium. He realizes that every day the number of fish doubles. On the third day he takes out one-third of the fish. On the fifth day he takes out one-fourth of the fish. On the seventh day he adds 15 more fish. How many fish in total does he have?
A: Start by finding how many fish were in the aquarium on the third day 6 * 2 * 2 = 24. On day three, Jason took out one - third of the fish 24 / 3 = 8. So at the end of day three, he has 24 - 8 = 16 fish. On day five he has 16 * 2 * 2 = 64 fish, but he takes out one - fourth. So he took out 64 / 4 = 16 fishes. So at the end of day five, he has 64 - 16 = 48 fish. On day seven he has 48 * 2 * 2 = 192 fish. He adds in 15 more, so he has 192 + 15 = 207 fish in total. The answer is 207.
Question: There were 100 jelly beans in a bag to be given away on Halloween. Out of the 40 children taking part in the Halloween celebration, 80% were allowed to draw jelly beans from the bag. Each child drew two jelly beans out of the bag. How many jelly beans remained in the bag after the children took their share?
Answer: Out of the 40 children taking part in the Halloween celebration, 80% were allowed to draw jelly beans from the bag, a total of 80 / 100 * 40 = 32 children. If each of the 32 children drew two jelly beans out of the bag, they drew a total of 32 * 2 = 64 jelly beans from the bag. The total number of jelly beans that remained is 100 - 64 = 36. The answer is 36.
[Question]Martha met Ellen in the grocery store alone and asked her age. Martha realized she was twice as old as Ellen will be in six years. If Ellen is 10 years old now, calculate Martha's age now.

Q: Lily has 5 lottery tickets to sell. She sells the first ticket for $1. She then sells each successive ticket for a dollar more than the previous ticket. She plans to keep a $4 profit and give the remaining money as the prize. How much money will the winner of the lottery receive?
A: The second ticket sold will cost $1 + $1 = $2. The third ticket sold will cost $2 + $1 = $3. The fourth ticket sold will cost $3 + $1 = $4. The fifth ticket sold will cost $4 + $1 = $5. The total money collected is $1 + $2 + $3 + $4 + $5 = $15. After taking profit, the total prize money will be $15 - $4 = $11. The answer is 11.
