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

### Instruction:
Bob enters cycling competitions every single week and hopes to win the 100 dollar grand prize each time. For the first 2 weeks, he managed first place and got 100 dollars each week. He is saving up for a puppy that costs 1000 dollars. What is the minimum number of additional weeks Bob must win first place?

### Response:
 Wiki 1 na 2 = wiki 2
1000 dola / 100 dola kwa wiki = 10 wiki
10 wiki - 2 wiki = 8 wiki
Bob anahitaji kushinda mashindano kwa angalau wiki 8 zaidi.
