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

### Instruction:
Jason joined the military when he turned 18.  It took him 8 years to raise to the rank of chief.  Then 25% longer than that to go from chief to master chief.  He then spent 10 years more in the military before retiring.  How old was he when he retired?

### Response:
 Ilimgia miaka 1.25*8=<<1.25*8=10>>10 kuwa mkuu mkuu.
Hivyo alitumia miaka 10+8=<<10+8=18>>18 kufikia cheo cha mkuu mkuu tangu alipojiunga.
Hivyo alihudumu kwa miaka 18+10=<<18+10=28>>28.
Hivyo alikuwa na umri wa miaka 28+18=<<28+18=46>>46 alipostaafu.
