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

### Instruction:
In Sam's collection, there are ten more black pens than blue pens and twice as many blue pens as pencils. There are also eight pencils and two fewer red pens than pencils. How many pens in all are there in Sam's collection?

### Response:
 8 x 2 = <<8*2=16>>16 ni idadi ya kalamu za bluu.
16 + 10 = <<16+10=26>>26 ni idadi ya kalamu za nyeusi.
8 - 2 = <<8-2=6>>6 ni idadi ya kalamu za nyekundu.
Hivyo, kuna jumla ya kalamu 16 + 26 + 6 = <<16+26+6=48>>48 katika mkusanyiko wa Sam.
