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

### Instruction:
In a class of 300 students, the number of smoking teens is 40% of the class. In a year, 70% of the smoking students are hospitalized from smoking-related complications. Calculate the total number of smoking students from the class who have not been hospitalized from smoking-related complications.

### Response:
 Ikiwa kuna wanafunzi 300 katika darasa, na idadi ya vijana wanaovuta sigara ni 40% ya darasa, basi kuna 40/100*300 = <<40/100*300=120>>120 wanafunzi wanaovuta sigara.
Kwa mwaka, 70% ya wanafunzi wanaovuta sigara wamehifadhiwa hospitalini kutokana na matatizo yanayohusiana na uvutaji sigara, jumla ya wanafunzi 70/100*120 = <<70/100*120=84>>84.
Idadi ya wanafunzi wanaovuta sigara ambao hawajahifadhiwa hospitalini kutokana na matatizo yanayohusiana na uvutaji sigara ni 120-84 = <<120-84=36>>36
