 <translate> 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.
Thus, the answer is 145. <yor> Níwọ̀n bó ti jẹ́ pé ẹja tí Tony ní pọ̀ ní ìlọ́po mẹ́ta ẹja tí Billy ní, ìyẹn túmọ̀ sí pé ẹja tí Tony ní pọ̀ ní ìlọ́po mẹ́wàá.
