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

### Instruction:
There's an online sale where you get $10 for every $100 that you spend. If you make a purchase of $250 before discounts, how much did you end up paying?

### Response:
 Ikiwa kwa kila $100 ninayotumia ninaokoa $10, basi kwa $250 niliyotumia nitapata $10*2=$20
Ikiwa jumla yangu ilikuwa $250, basi mwishowe nililipa $250-$20=$<<250-20=230>>230
