Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
There are 200 snakes in a park. There are three times as many pythons as boa constrictors. If there 40 boa constrictors and the rest of the snakes are rattlesnakes, calculate the total number of rattlesnakes in the park.

### Response:
 Ikiwa kuna nyoka wa boa constrictor 40, kuna nyoka wa chatu 3*40 = <<40*3=120>>120.
Jumla, idadi ya nyoka wa chatu na nyoka wa boa constrictor ni 120+40 = <<120+40=160>>160.
Ikiwa kuna nyoka 200 katika mbuga, idadi ya nyoka wa chatu ni 200-160 = <<200-160=40>>40.
