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

### Instruction:
Tom spends $250 to buy gems in a game he plays.  The game gives 100 gems for each dollar you spend.  Since he bought so many gems he got a 20% bonus of more gems. How many gems did he end up with?

### Response:
 Alinunua vito 250*100=<<250*100=25000>>25000
Baada ya ziada, alipata vito vingine 25000*.2=<<25000*.2=5000>>5000
Hivyo alikuwa na jumla ya vito 25000+5000=<<25000+5000=30000>>30000
