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

### Instruction:
Mathilda is determined to pay back the money she owes a friend so she decides to pay an initial installment of $125. If she still has 75% left to pay, how much did she owe originally?

### Response:
 Asilimia inamaanisha kwa kila 100, kwa hivyo ikiwa bado anadaiwa 75%, lazima awe amelipa 100% - 75% = 25% ya kiasi cha awali.
25% ya kiasi cha awali = (25/100)*kiasi cha awali = $125
Kuzidisha pande zote za equation na (100/25) inatoa: kiasi cha awali = (100/25)*$125 = $500
