Question: Adam had a farm with animals. He had 12 cows and twice as many sheep. He decided to buy 3 pigs for every sheep he had. How many animals were on the farm after the transaction?
Answer: Adam had twice as many sheep as the cows, so 2 sheep / cow * 12 cows = 24 sheep. For every sheep, he bought 3 pigs, so he bought 3 pigs / sheep * 24 sheep = 72 pigs. In total on the farm, there were 72 pigs + 24 sheep + 12 cows = 108 animals. The answer is 108.
[Question]Alexandra bought 8 magazines at the bookstore on Friday. On Saturday, she went back and bought 12 more. Sunday morning, she saw that the store was having a sale and she bought four times the number of magazines she did on Friday. Later that day she discovered that her dog had chewed up 4 of the magazines. How many magazines does she have now?
[Answer]By adding Friday and Saturday, Alexandra bought 12 + 8 = 20 magazines. On Sunday she buys 8 * 4 = 32 magazines. Before her dog got to them she had 12 + 8 + 32 = 52 magazines. After her dog chewed up some she had 52 - 4 = 48 magazines. The answer is 48.
Q: Randy got 90, 98, 92, and 94 in his first four quizzes. His goal is to get a 94 average on his 5 quizzes. What score should he get in the fifth quiz to reach his desired average?
A: Since Randy wants to get an average of 94, then the sum of the 5 quizzes should be 94 x 5 = 470. The sum of Randy's score for the first four quizzes is 90 + 98 + 92 + 94 = 374. Thus, Randy needs to get 470 - 374 = 96 in his fifth quiz. The answer is 96.
Question: Utopia National Park hosted 30,000 elephants on Friday night. The next morning, there was a 4-hour elephant exodus out of the park, at a constant rate of 2,880 elephants/hour. Over the next 7-hour period, new elephants entered the park at a constant rate. If the final number of elephants in the park was 28,980, at what rate did the new elephants enter the park?
Answer: The Saturday morning exodus out of the park comprised 4 * 2880 = 11520 elephants. This means that after the exodus, the park was left with 30000 - 11520 = 18480 elephants. Since the final number of elephants was 28,980, the new elephants that entered were 28980 - 18480 = 10500. The rate at which the new elephants entered the park was therefore 10500 / 7 = 1500 elephants / hour. The answer is 1500.

[Question]Johnson owns a hectare cornfield that can yield 80 corn every two months, while his neighbor owns a two-hectare cornfield and each hectare can yield twice the amount as Johnson. How much corn can they harvest altogether after six months?
[Answer]
Each hectare of Johnson's neighbor can yield 80 x 2 = 160 corns every two months. So, the neighbor's two - hectare cornfield can yield a total of 160 x 2 = 320 corns every two months. They yield a total of 80 + 320 = 400 corns. Therefore, They can harvest 400 x 3 = 1200 corns altogether. The answer is 1200.
