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

### Instruction:
 Katika mgahawa, kikombe kimoja cha kahawa ni $6 na kipande cha cheesecake ni $10. Mteja anapopata pamoja, anapata punguzo la 25%. Bei ya mwisho ya seti hiyo ni kiasi gani?


### Response:
 Cheesecake na kahawa zote mbili gharama yake ni 10 + 6 = $16.
Punguzo kwa vitu hivi ni 25/100 * 16 = $<<25/100*16=4>>4.
Hivyo, bei ya mwisho ya cheesecake na kahawa ni 16 - 4 = $<<16-4=12>>12.
