Paul is a chicken trader. One week he had 80 chickens in total to sell at the market. Before he left the farm, he sold his neighbor 12 chickens. At the gate, before the market opens, he got a quick customer and sold another 25 chickens. How many chickens was Paul left with to sell at the market? Give the rationale and then the answer.
Let's think step by step. Before the market opened, Paul sold 12 + 25 = 37 chickens. So he had 80 - 37 = 43 chickens left to sell at the market.. The answer is: 43.

Jesse is playing with a pile of building blocks. He first builds a building with 80 building blocks. Then he builds a farmhouse with 123 building blocks. He adds a fenced-in area next to the farm made of 57 building blocks. If Jesse has 84 building blocks left, how many building blocks did he start with? Give the rationale and then the answer.
Let's think step by step. Jesse built three structures out of building blocks, 80 + 123 + 57 = 260 building blocks. Jesse started with 260 + 84 leftover building blocks = 344 building blocks that Jesse had originally.. The answer is: 344.

Tom's cat is 8 years old. His rabbit is half the age of his cat. His dog is three times as old as his rabbit. How old is the dog? Give the rationale and then the answer.
