Correct Answer: A
Explanation:
We can see the months are listed along the bottom axis. We can also see the scale on the left ranges from 0 to 25. These numbers represent the number of enrollments.
Now, to find the approximate number of enrollments for April, we will first find April. We can see it is the last month listed.
Now, we can see the value of the bar is between 20 and 25. We can also see that it is fairly close to 20.
Therefore, we can approximate the number of enrollments for April is 21.
