### 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:
 เขาซื้ออัญมณี 250*100=<<250*100=25000>>25000 เหรียญ
เขาได้รับโบนัสอัญมณี 25,000*.2=5,000 เหรียญ
ดังนั้นเขาได้รับทั้งหมด 25,000+5,000=<<25000+5000=30000>>30,000 เหรียญ
