Question 136956
To determine the number of deer in a game preserve, a conservationist catches 804 deer, tags them and lets them loose. Later, 549 deer are caught; 183 of them are tagged.  How many deer are in the preserve? 
----------------
population/(tagged&released) = (# caught)/(# tagged in # caught)
--------------
population/804 = 549/183
pop = 804[549/183)
pop = 2412 deer
