Answer:
A.) About 90
Step-by-step explanation:
From the given table, the biologist tagged 150 trout. Also, he recaptured a total of 100 trouts of which 60 were recaptured with tags.
Thus, let the trout population in the lake be represented by x, 
      =
 =  
Cross multiply to have;
  100 × x = 60 × 150
   100x = 9000
Divide both sides by 100,
  x = 
     = 90
Therefore, the trout population is about 90 in the lake.
