Q: A city has a population of 300,000. 50,000 people immigrate to the country and then 30,000 people leave. After that 1/8 of the population gets pregnant and 1/4 of those people have twins. How many people are there after the births?
A: There was a net immigration to the country of 50,000 - 30,000 = 20,000. So the total number of people before birth is 300,000 + 20,000 = 320,000. That means 320,000 / 8 = 40,000 get pregnant. So 40,000 / 4 = 10,000 have twins. So that means they have 10,000 * 2 = 20,000 children. There are 40,000 - 10,000 = 30,000 children from single births. So the total number of people is 320,000 + 30,000 + 20,000 = 370,000. The answer is 370000.
Question: Tedra is harvesting his tomatoes. He harvests 400 kg on Wednesday, and half as much on Thursday. He harvests a total of 2000 kg on Wednesday, Thursday, and Friday. How many tomatoes of the number he harvested on Friday are remaining if he gives away 700kg of them to his friends?
Answer: Tedra harvests 1 / 2 * 400 kg = 200 kg of tomatoes on Thursday. Tedra harvests 2000 kg - 400 kg - 200 kg = 1400 kg of tomatoes on Friday. After giving away tomatoes to his friends, he is left with 1400 kg - 700 kg = 700 kg of tomatoes. The answer is 700.
[Question]Rose bought her mother one dozen flowers. Two of the flowers are daisies. Three-fifths of the remaining flowers are tulips and the rest are sunflowers. How many sunflowers are there?
[Answer]One dozen of flowers is equal to 1 x 12 = 12 flowers. There are 12 - 2 = 10 flowers that are not daisies. So, 10 x 3 / 5 = 6 of the flowers are tulips. Therefore, there are 10 - 6 = 4 sunflowers. The answer is 4.

Question: Paul, a biology teacher, assigns 265 points in the first quarter. There are 4 times as many test points as quiz points, and 5 more quiz points than homework points. How many homework points are there in the first quarter?
Answer: Let x represent the number of homework points. Quiz:x + 5. Test:4(x + 5) = 4x + 20. Total:x + x + 5 + 4x + 20 = 265. 6x + 25 = 265. 6x = 240. x = 40 points. The answer is 40.
