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?

conversations.value: Since Tony has 3 times as many fish as Billy's 10, that means Tony has 3*10= 30 fish
  Sarah has 5 more fish than Tony's 30, meaning she has 5+30= 35 fish
  Bobby has twice as many fish as Sarah does, meaning he has 35*2=70 fish
  Therefore, altogether there are 10+30+35+70=145 fish
