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

### Instruction:
Bobby has an aquarium with twice as many fish as Sarah's has.  Sarah has 5 more fish in her aquarium than Tony does.  Tony has 3 times as many fish in his aquarium as Billy does.  Billy has 10 fish.  How many fish do all 4 people have put together?

### Response:
 Sarah ana samaki 5 zaidi ya samaki 30 za Tony
Kwa hivyo Sarah ana samaki 30+5=<<5+30=35>>35
Bobby ana samaki 2*35=<<2*35=70>>70
Kwa hivyo jumla wana samaki 10+30+35+70=<<10+30+35+70=145>>145
