An island has 12 fur seal rookeries (breeding places). To estimate the fur seal pup population in Rookery A, 6982 fur seal pups were tagged in early August. In late August, a sample of 700 pups was observed, and 245 these were found to have been previously tagged. Use a proportion to estimate the total number of fur seal pups in Rookery A.

The estimated total number of fur seal pups in Rookery A is____.

Presumably, the same percentage of seals was tagged as was found in the later sample. So,

6982/x = 245/700
