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

### Instruction:
 Lizzy alikuwa na $30. Alikopa $15 kwa rafiki yake. Atakuwa na kiasi gani ikiwa rafiki yake atarudisha pesa hiyo na riba ya 20%?


### Response:
 Lizzy alikuwa na $30-$15= $15 iliyobaki
Rafiki yake alirudisha $15*1.2= $18
Hivyo, alikuwa na $15+$18= $33
