<PRE><B>Question 304727</B>
Captured, tagged, and released 50 bears.
Next year random sample of 100 bears included only two tagged bears.


I think the answer should be 2500.


Basically, you set up a ratio.


2 is to 100 as 50 is to x.


Your equation becomes:


{{{2/100 = 50/x}}}


You cross multiply to get:


{{{2*x = 50*100}}}


You divide both sides of this equation by 2 to get:


{{{x = (50*100)/2 = 50*50 = 2500}}}
