Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: He saw 25 total vehicles because 12 plus 13 equals 25. He saw 100 wheels because 25 times 4 equals 100.
 The question and answer:
Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see?
The answer is 100
