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

### Instruction:
Pete has a bag with 10 marbles. 40% are blue and the rest are red. His friend will trade him two blue marbles for every red one. If Pete keeps 1 red marble, how many total marbles does he have after trading with his friend?

### Response:
 Pete ana mabulinge 10. Asilimia 40 ni buluu, hivyo 40% ya mabulinge ni 4. Hii inamaanisha ana mabulinge 4 ya buluu na 10-4 = <<10-4=6>>6 mabulinge ya nyekundu.
Ikiwa atabaki na nyekundu moja, atakuwa na mabulinge 5 ya nyekundu ya kufanya biashara.
Ikiwa atafanya biashara ya mabulinge mawili ya buluu kwa kila moja ya nyekundu, atapata mabulinge 2*5=<<2*5=10>>10 ya buluu.
Hivyo baada ya kufanya biashara na rafiki yake, atakuwa na mabulinge 10+1=<<10+1=11>>11.
