A biologist catches 41 fish in lake and tags them.
She returns and catches a new sample containing 50 fish only 7 of the fish tagged.
Based on this ratio, what is the approximate population of fish in the lake ?
:
let x = the population of fish in the lake
:
The total fish to tagged fish relationship
=
Cross multiply
7x = 41 * 50
7x = 2050
x = 2050/7
x ~ 293, approximately 300 fish in the lake
