At the moment there are 54,210 tagged birds in a certain wildlife refuge. If exactly 20 percent of all birds in the refuge are tagged, what percent of the untagged birds must be tagged so that half of all birds in the refuge are tagged?

Best ResponseYou've already chosen the best response.0In fact, if we're going to use numbers, let's say there are 100 birds. This means that 20 are tagged and 80 are untagged. For 1/2 the birds to be tagged, we need 50 tagged birds. In other words, we need 30 additional tagged birds. So, from the 80 untagged, we need to tag 30 birds. 30/80 = 3/8 = 37.5% 9 mins. and no help thats crazy O.o
