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?
Let’s work this out in a step by step way to be sure we have the right answer.
108
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 answer is 108
