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

### Instruction:
 Kenneth alitumia 10% ya kipato chake wiki hii kununua kifaa cha kuchezea michezo. Ikiwa amebakiwa na $405, kiasi gani alikuwa amepata?


### Response:
 Kwa kuwa Kenneth alitumia 10%, basi kipato chake ni 100% - 10% = 90% ya kipato chake kilichobaki.
Kwa kuwa 90% ni sawa na $405, basi 10% ni $405/9 = $<<405/9=45>>45.
Hivyo, kipato cha Kenneth ni $45 x 10 = $<<45*10=450>>450.
