Answer: We can use a proportion to estimate the total number of fur seal pups in Rookery A. Let x be the total number of fur seal pups in Rookery A. Then we have:
6269/x = 221/1100
Cross-multiplying, we get:
221x = 6269 * 1100
Dividing both sides by 221, we get:
x = 6269 * 1100 / 221
Simplifying, we get:
x = 31,245.25
Rounding to the nearest whole number, we get:
x ≈ 31,245
Therefore, the estimated total number of fur seal pups in Rookery A is 31,245.
