Suppose biologists tagged 53 penguins in antarctica during mating season. the next year, they caught 82 penguins and found that 11 of them had tags. estimate the total number of penguins in the area. a) 446 b) 395 c) 405 d) 353

We approach this problem by doing a simple proportion. If the biologists found 11 tagged out of 82 penguins, then we can estimate that the same percentage of penguins were tagged during mating season.

The proportion should therefore be  where x is the total number of penguins. Solving this proportion we can find the value of x:





Since there is no such thing as half a penguin, we can round off the answer to the nearest unit.

ANSWER: B. We can estimate that there are 395 penguins in the area.
