### Instruction:
 Bob alinunua mbwa 2 wa maonyesho kwa $250.00 kila mmoja ili kuzaliana kama biashara ya upande. Mwana-dume amejifungua watoto 6. Ikiwa anauza kila mtoto kwa $350.00, faida yake jumla ni kiasi gani?


### Response:
 Alinunua mbwa 2 kwa $250.00 kila mmoja hivyo gharama yake ni 2*250 = $<<2*250=500.00>>500.00
Anauza kila mtoto kwa $350.00 hivyo atapata 6*350 = $<<6*350=2100.00>>2,100.00
Ametengeneza $2,100 kwa watoto lakini alitumia $500.00 kununua mbwa hivyo faida yake jumla ni 2,100-500 = $<<2100-500=1600.00>>1,600.00
