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

### Instruction:
Ben has $2000 for his business operations costs. He orders goods from his supplier and writes them a cheque for $600. His debtor pays him $800 from the purchases they had made on credit. Mr. Ben then decides to do equipment maintenance and spends $1200 on the whole operation. How much money is Mr. Ben remaining with?

### Response:
 Wakati Bwana Ben anaandika hundi, anabaki na $2000-$600=$<<2000-600=1400>>1400
Mteja wake anamlipa $800, hivyo kuongeza mtaji wake wa uendeshaji wa biashara hadi $1400+$800=$2200
Baada ya kutumia $1200, anabaki na $2200-$1200=$<<2200-1200=1000>>1000 kwa gharama za uendeshaji wa biashara baada ya matengenezo.
