Question

In City Lake, researchers caught, marked, and released 258 bass. Later, they took a sample of 130 bass and found that 26 were marked. Estimate the number of bass in the lake.

Answer 1

26 out of 130 were marked.

Divide 26 by 130:

26/130 = 0.20

20% of the bass caught were tagged.

Now divide the total amount caught and tagged by that percentage:

258 / 0.20 = 1,290

There are 1,290 bass in the lake.
