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

### Instruction:
 Usiku wa dansi, wanafunzi 400 walihudhuria kwenye sherehe. Asilimia 70 ya wanafunzi waliohudhuria walikuwa wamealikwa. Ikiwa asilimia 40 ya wale walioalikwa walipokonywa mwaliko na hawakuruhusiwa kuingia kwenye sherehe, wanafunzi wangapi walioalikwa walihudhuria sherehe?


### Response:
 Usiku wa dansi, wanafunzi 70/100*400 = <<70/100*400=280>>280 waliohudhuria sherehe walikuwa wamealikwa.
Ikiwa asilimia 40 ya wale walioalikwa walipokonywa mwaliko, kulikuwa na wanafunzi 40/100*280 = <<40/100*280=112>>112 waliohudhuria sherehe na walioalikwa.
Idadi ya wanafunzi walioalikwa waliohudhuria sherehe ni 280-112 = <<280-112=168>>168.
