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, and Ben are fond of collecting stickers. Karl has 25 stickers. Ryan has 20 more stickers than Karl. Ben has 10 fewer stickers than Ryan. They placed all their stickers in one sticker book. How many stickers did they place altogether?

### 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.
