Use a proportion to solve

of the bear

population on the Keweenaw Peninsula, conservationists

captured, tagged, and released 50 bears. One year later, a

random sample of 100 bears included only 2 tagged bears.

What is the conservationist’s estimate of the size of the

bear population

**Azteca**, Friday, July 17, 2009 at 2:48am2/50=100/x cross multiply

2x=500 divide by 2

x=250 result

**Reiny**, Friday, July 17, 2009 at 7:34amAzteca, 50(100) = 2500 not 250

or

it appears that 2/100 or 2% of the bear population was tagged.

So the 50 must be 2% of the bear population

.02x = 50

x = 50/.02 = 2500

**richard**, Friday, November 1, 2013 at 5:53pmI think that the answer is 2/100=50/2 cross multiply it to make it 2x2=4 and 50x 100 is 5000 or 2/100= 2/50 cross multiply it to get 100 and 200 divide it by 2 to get 100 and to get 50...I think i messsed up :/
