Explanation:
Mean is the average of a dataset.
The question gives you the mean (average) of the cost of a dog's annual visit. As you can see at A New Leash of Life, the mean (average) is $300.75, whereas at No Ruff Stuff, the mean (average) is $224.65.
Since the question is only asking for a statement that matches the info above, the only option that matches is the first option.
