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

### Instruction:
 Donald alikwenda duka la kompyuta. Alikuta punguzo la 15% kwenye bei ya kompyuta ndogo anayotaka kununua. Ikiwa kompyuta ndogo awali ilikuwa inagharimu $800, atalipa kiasi gani kwa kompyuta hiyo?


### Response:
 Kulikuwa na $800 x 15/100 = $<<800*15/100=120>>120.
Hivyo, Donald atalipa $800 - $120 = $<<800-120=680>>680.
