Use the image to answer the question. A bar graph shows pet ownership. The x-axis shows type of pet and represents dog, cat, golfish, and hamster. The y-axis represents number of students and ranges from 0 to 11 in increments of 1. The data shows 10 dogs; 8 cats; 2 goldfish; and 3 hamsters. Use the graph to determine the difference in the percentage of students who have dogs for pets and the percentage of students who have hamsters for pets. Round the percentages to the tenths place.

To find the percentage of students who have dogs as pets, we divide the number of students with dogs (10) by the total number of students (10 + 8 + 2 + 3 = 23), then multiply by 100:
(10 / 23) * 100 = 43.5%
To find the percentage of students who have hamsters as pets, we divide the number of students with hamsters (3) by the total number of students (23), then multiply by 100:
(3 / 23) * 100 = 13.0%
The difference in percentage of students who have dogs as pets and students who have hamsters as pets is:
43.5% - 13.0% = 30.5%
Therefore, the difference in percentage is 30.5%.
