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

### Instruction:
Steve's new book sells 1,000,000 copies.  He got an advance to pay for 100,000 copies. He gets $2 for each copy of the book sold.  His agent takes 10% of that.  How much money did he keep not counting the money from the advance?

### Response:
 Aliuza 1,000,000-100,000=900,000 bila kuhesabu malipo ya awali.
Hivyo, alipata 900,000*2=$1,800,000 kutokana na kuuza vitabu.
Hivyo, alikiweka 1,800,000-180,000=$1,620,000 kutokana na kuuza vitabu.
