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

### Instruction:
 Reginald anauza matofaa. Anauza kila tufaha kwa $1.25. Anapanga kutumia faida yake kusaidia kurekebisha baiskeli yake. Baiskeli yake iligharimu $80 na gharama za ukarabati ni 25% ya gharama ya baiskeli yake. Baada ya kulipa gharama za ukarabati, 1/5 ya pesa alizopata zimesalia. Amewauza tufaha ngapi?



### Response:
 Gharama za ukarabati wa baiskeli ni $20 kwa sababu 80 x .25 = <<80*.25=20>>20
Wito kiasi anachopata kuwa e. Tunajua kuwa e - 20 = 1/5e
Hivyo 5e - 100 = e
Hivyo, 4e = 100
Hivyo, e = <<25=25>>25
Hivyo, ameuza tufaha 20 kwa sababu 25 / 1.25 = <<25/1.25=20>>20
