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? Give me reasons, before answering the question
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. So the final answer is 108.
