8 is 16% of the 50 sampled.
That means that 200 is 16% of the whole population.
0.16p = 200

40 out of 72 fish in one lake were tagged by a wildlife researcher. At a second lake, 260 fish were tagged. If fish were tagged at proportional rates in the two lakes, how many fish were in the second lake?
