If seven more rabbits are added to the thirteen in the cage, the number of rabbits in the cage will be 1/3 the number of rabbits Jasper saw in the park today. How many rabbits did Jasper see in the park today? Let's think first. Chain of thought:
If seven more rabbits are added to the thirteen in the cage, the total number becomes 7 + 13 = 20. Triple the number of rabbits in the cage is 3 * 20 = 60, the same as the number of rabbits that Jasper saw at the park today.
Therefore, the answer is 60.
