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

### Instruction:
 Vince anamiliki saluni ya nywele na anapata $18 kwa kila mteja. Gharama zake za kila mwezi ni $280 kwa kodi na umeme na 20% ya mapato yake hutengwa kwa burudani na kupumzika. Atahifadhi kiasi gani ikiwa anahudumia wateja 80 kwa mwezi?


### Response:
 Mwezi huu, Vince anapata $18 x 80 = $<<18*80=1440>>1440 kwa kuhudumia wateja 80.
Kiasi anachotenga kwa burudani na kupumzika ni 20/100 x $1440 = $<<20/100*1440=288>>288.
Hivyo, gharama zake za kila mwezi ni $280 + $288 = $<<280+288=568>>568.
Hivyo, Vince anahifadhi $1440 - $568 = $<<1440-568=872>>872.
