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

### Instruction:
The number of students who wish to go on a skiing trip is twice as many as those who wish to go on a scavenger hunting trip. If there are 4000 students who wish to go on the scavenger hunting trip, how many students are there altogether?

### Response:
 Ikiwa kuna wanafunzi 4000 wanaotaka kwenda kwenye safari ya kutafuta vitu, idadi ya wanafunzi wanaotaka kwenda kwenye safari ya kuteleza ni 2*4000 = 8000.
Jumla ya wanafunzi ni 4000+8000 = <<4000+8000=12000>>12000.
