An island has 12 fur seal rookeries (breeding places). To estimate the fur seal pup
population in Rookery A, 5611 fur seal pups were tagged in early August. In late August, a
sample of 1000 pups was observed, and 163 of these were found to have been previously
tagged. Use a proportion to estimate the total number of fur seal pups in Rookery A.
using a proportion
1,000/163=x/5,611
solve for x
x=(1,000/163)*5,611
x=34,423
answer is 34,423 fur seal pups
