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

### Instruction:
 Baada ya safari, Bi. Nalani aliwapeleka wanafunzi kwenye mgahawa na kuwaambia wanaweza kuagiza burger au hot dog. Ikiwa idadi ya wanafunzi walioagiza burger ilikuwa 30, mara mbili idadi ya wanafunzi walioagiza hot dog, hesabu idadi ya wanafunzi kwenye mgahawa.


### Response:
 Ikiwa wanafunzi 30 walioagiza burger walikuwa mara mbili ya idadi ya wanafunzi walioagiza hot dog, basi 30/2 = <<30/2=15>>15 wanafunzi walioagiza hot dog.
Jumla ya wanafunzi ni 15 + 30 = <<15+30=45>>45, kwani wote waliamuru chakula.
