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

### Instruction:
Alfonso earns $6 each day walking his aunt’s dog. He is saving to buy a mountain bike helmet for $340. Currently, he already has $40. If he walks his aunt's dog 5 days a week, in how many weeks should Alfonso work to buy his mountain bike?

### Response:
 Katika wiki, Alfonso anapata $6 x 5 = $<<6*5=30>>30.
Jumla ya kiasi anachohitaji kufanya kazi ili kununua baiskeli ni $340 - $40 = $<<300=300>>300.
Hivyo, anahitaji kufanya kazi kwa wiki $300/$30 = <<300/30=10>>10 ili kununua baiskeli.
