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

### Instruction:
 Joe anauza sandwichi za hamu na jibini kwa $1.50. Ikiwa kipande kimoja cha mkate kinagharimu $0.15, kipande kimoja cha hamu kinagharimu $0.25 na kipande kimoja cha jibini kinagharimu $0.35, senti ngapi inagharimu Joe kutengeneza sandwichi moja yenye kipande kimoja cha kila protini?


### Response:
 Kwanza tafuta gharama ya vipande viwili vya mkate: $0.15/kipande * vipande 2 = $<<0.15*2=0.30>>0.30
Kisha ongeza gharama ya kipande kimoja cha hamu na jibini: $0.30 + $0.25 + $0.35 = $<<0.30+0.25+0.35=0.90>>0.90
