On the scale on the left are the enrolments and on the scale on the right are the appropriations per student.
Total Appropriations = Number of Enrolments * Appropriations per student
Of the years 1997, 1999, and 2001, the least total appropriations for public school students in Nation Z occurred in ____
We have to compare the first 3 bars. Just looking at the graph, we see that in 1997, the enrolment was the least and the appropriation per student was the least too. Then automatically, total appropriations in 1997 would be the least. ANSWER
Of the years 2003, 2005, and 2007, the greatest total appropriations for public school students in Nation Z occurred in ____
Now we have to compare the last 3 bars. Appropriation per student for 2005 and 2007 are the same but enrolment is 2007 is higher so we ignore 2005.
Now 2003 has higher appropriation per student but 2007 has higher enrolment. So we must calculate here.
2003 - Total = 520 * 1600 = 8,32,000
2007 - Total = 570 * 1400 = 7,98,000
Total for 2003 is higher. ANSWER
