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

### Instruction:
 Karl, Ryan, na Ben wanapenda kukusanya stika. Karl ana stika 25. Ryan ana stika 20 zaidi ya Karl. Ben ana stika 10 chini ya Ryan. Waliziweka stika zao zote katika kitabu kimoja cha stika. Stika ngapi waliziweka pamoja?


### Response:
 Ryan ana stika 25 + 20 = <<25+20=45>>45.
Ben ana stika 45 - 10 = <<45-10=35>>35.
Hivyo, jumla ya stika walizoweka pamoja ni 25 + 45 + 35 = <<25+45+35=105>>105.
