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

### Instruction:
 Wakati akipita karibu na duka, Miley aligundua kuwa mfuko ambao ulikuwa unauzwa kwa $150 wiki iliyopita sasa unauzwa kwa $135. Asilimia ngapi ni punguzo?


### Response:
 Mfuko sasa unauzwa kwa $150 - $135 = $<<150-135=15>>15 chini.
Punguzo ni 15/150 = <<15/150=0.1>>0.1
Asilimia ya punguzo ni 0.1 x 100% = 10%
