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

### Instruction:
 Mtu mmoja alikopa kiasi fulani cha pesa kwa mwaka kwa kiwango cha riba cha 12%. Ikiwa riba jumla ni $1500, kiasi cha pesa kilichokopwa awali kilikuwa kiasi gani?


### Response:
 Hebu X iwe bei ya kiasi cha pesa kilichokopwa. Riba ni X * .12 = $1500.
Hivyo kiasi cha pesa kilichokopwa ni X = $1500 / .12 = $<<1500/.12=12500>>12500.
