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

### Instruction:
Nick is trying to raise money for a charity. He is selling candy bars for $5. He is also selling chocolate oranges for $10. He wants to raise $1000. He only had 20 chocolate oranges that he sold out. How many candy bars does Nick need to sell to reach his goal?

### Response:
 Nick amepata $20 * $10 = $<<20*10=200>>200 kutokana na machungwa ya chokoleti.
Anahitaji kukusanya $1000 - $200 = $<<1000-200=800>>800 zaidi.
Anahitaji kuuza jumla ya mabaa ya pipi $800 / $5 = <<800/5=160>>160 ili kufikia lengo lake.
