Answer

Explanation:

Step1: Calculate percentage for Koala

The formula for percentage is $\frac{\text{Number of attendees for Koala}}{\text{Total number of attendees}}\times100%$. The total number of attendees is 1600 and for Koala is 768. So the percentage is $\frac{768}{1600}\times 100% = 48%$.

Step2: Calculate percentage for Jaguar

Using the same formula, with 544 attendees for Jaguar, the percentage is $\frac{544}{1600}\times 100%= 34%$.

Step3: Calculate percentage for Anteater

For Anteater with 128 attendees, the percentage is $\frac{128}{1600}\times 100% = 8%$.

Step4: Calculate percentage for Gorilla

For Gorilla with 160 attendees, the percentage is $\frac{160}{1600}\times 100%= 10%$.

Answer:

Type of animal Percentage
Koala 48%
Jaguar 34%
Anteater 8%
Gorilla 10%

(Note: For part (b) of constructing a percent - bar graph, it is more of a graphical task. But the percentages calculated above are the key data for constructing it. The bars for Koala, Jaguar, Anteater and Gorilla should be drawn to represent 48%, 34%, 8% and 10% respectively on the graph.)
