To determine the number of deer in a game preserve, a conservationist catches 823 deer, tags them and lets them loose.
Later, 692 deer are caught; 173 of them are tagged.
How many deer are in the preserve?
:
Let d = actual number of deer
:
Write ratio equation:
d%2F823 = 692%2F173
Cross multiply
173d = 823 * 692
173d = 569516
d = 569516/173
d = 3,292 deer
