Answer:

\boxed{10.4 \%}

Step-by-step explanation:

\text{Percent error} = \frac{\lvert\text{Predicted - Actual}\lvert}{\text{Actual}} \times 100\%

Data:

Predicted = 275 lb

  Actual = 307 lb

Calculation

\text{Percent error} = \frac{\lvert275 - 307\lvert}{307} \times 100\%\\\\= \frac{\lvert-32\lvert}{307} \times 100\%\\\\= \frac{32}{307} \times 100\%\\

= 0.104 × 100 %

= 10.4 %

The percent error of the zookeeper's prediction was \boxed{10.4 \%}.
