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

### Instruction:
 Jim ananunua pakiti ya kusafisha gari 20. Kwa kuwa alinunua pakiti, anapaswa kulipa 60%. Kusafisha gari kawaida gharama dola 15. Alilipa kiasi gani kwa pakiti hiyo?


### Response:
 Kusafisha gari kwake gharama 20 * 15 = $<<20*15=300>>300
Hivyo anapaswa kulipa 300 * 0.6 = $<<300*.6=180>>180
