Answer 3

Calculation of Percentage Increase in Animals at the Zoo

To calculate the percentage increase in the number of animals at the zoo, we need to find the difference between the initial number of animals and the final number of animals, and then divide that difference by the initial number of animals. Finally, we multiply the result by 100 to get the percentage increase.

Given that there were initially 120 animals at the zoo and then an additional number of animals were brought in, resulting in a total of 150 animals, we can calculate the percentage increase as follows:

Step 1: Find the difference in the number of animals: 150 - 120 = 30

Step 2: Calculate the percentage increase: (30 / 120) * 100 = 25

Therefore, the number of animals at the zoo increased by 25%.
