Correct Answer: D
Explanation:
We can see the bars represent the number of enrollments in the 12th grade for different years.
To find the difference of enrollments from 2012 to 2015, we will first find the number of enrollments from those years, then we will subtract them.
So, we can see the number of enrollments in 2012 was 89. We can see the number of enrollments in 2015 was 148. Now, we subtract. We get
148 − 89 = 59
Therefore, the difference of 12th grade enrollments from 2012 to 2015 is 59.
