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

### Instruction:
A trader has 55 bags of rice in stock. She sells off some bags of rice and restocks 132 bags of rice. How many bags of rice did she sell if she now has 164 bags of rice?

### Response:
 Alikuwa na mifuko 55 na akainunua mifuko 132, jumla ya mifuko 55+132 = <<55+132=187>>187
Hata hivyo, sasa ana mifuko 164, maana yake ameuza mifuko 187-164 = 23.
