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?
If seven more rabbits are added to the thirteen in the cage, the total number becomes 7+13 = <<7+13=20>>20
Triple the number of rabbits in the cage is 3*20 = <<3*20=60>>60, the same as the number of rabbits that Jasper saw at the park today.
#### 60
