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

### Instruction:
Kimberley, Ela, and Houston all are sent to collect firewood by their grammy. Kimberley collects ten pounds of firewood, and Houston collects 12 pounds of firewood. If the three of them managed to collect a total of 35 pounds of firewood, how many pounds were collected by Ela?

### Response:
 Kimberley amekusanya kuni za paundi kumi na Houston amekusanya kuni za paundi kumi na mbili, hivyo pamoja wamekusanya kuni za paundi ishirini na mbili.
Unajua kwamba wamekusanya jumla ya paundi thelathini na tano za kuni, hivyo Ela amekusanya kuni za paundi thelathini na tano - paundi ishirini na mbili = <<35-22=13>>13 paundi za kuni.
