Key Insights

1. Enrollment in Nation Z's public schools increased every measured year from 1997 to 2007, resulting in more total students annually.
2. Appropriations per student peaked in 1999 and then steadily declined through 2007.
3. Despite growing enrollment, the decreasing per-student funding altered the trend in total appropriations given to schools.
4. For years 1997/1999/2001, total appropriations (enrollment x per-student funding) were lowest in 1997 because both enrollment and funding levels were lower than in 1999 and 2001.
5. For years 2003/2005/2007, total appropriations were highest in 2003: rising enrollment combined with a still relatively high per-student rate, while later years had higher enrollment but much lower per-student funding.
6. The period shows how per-student dollars can decline even as overall resources rise, due to large increases in the student body.

Step-by-Step Solution

Question 1: Finding the Year with Least Total Appropriations (1997-2001)

Complete Statement:

Of the years 1997, 1999, and 2001, the least total appropriations for public school students in Nation Z occurred in [BLANK].

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: total appropriations for public school students
  • Meaning: The total amount of money spent for all public school students combined in one year.
  • Relation to Chart: Not directly shown on the chart; must multiply enrollment by appropriations per student.
  • Important Implications: We need both enrollment and per-student appropriations for each year to calculate the required totals.

• Statement Breakdown 2:
  • Key Phrase: least ... occurred in
  • Meaning: We are looking for the smallest calculated total appropriations among the given years.
  • Relation to Chart: We must compare the total amounts calculated for each year indicated.
  • Important Implications: Comparison is between three calculated values, not chart values directly.

• What is needed: Which year (out of 1997, 1999, and 2001) had the smallest total appropriations.

Solution:

• Condensed Solution Implementation:
  For each year, calculate total appropriations by multiplying enrollment (thousands of students) by appropriations per student, then compare the totals.
• Necessary Data points:
  1997: 410 thousand students, $1,700 per student. 1999: 420 thousand students, $1,850 per student. 2001: 460 thousand students, $1,750 per student.
• Calculations Estimations:
  1997: \(410 \times \$1,700 = \$697,000\) thousand. 1999: \(420 \times \$1,850 = \$777,000\) thousand. 2001: \(460 \times \$1,750 = \$805,000\) thousand.
• Comparison to Answer Choices:
  Among these, $697,000 thousand (1997) is the least; so 1997 is the answer.

FINAL ANSWER Blank 1: 1997

Question 2: Finding the Year with Greatest Total Appropriations (2003-2007)

Complete Statement:

Of the years 2003, 2005, and 2007, the greatest total appropriations for public school students in Nation Z occurred in [BLANK].

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: total appropriations for public school students
  • Meaning: The total amount of money spent for all public school students combined in one year.
  • Relation to Chart: Not directly shown on the chart; must multiply enrollment by appropriations per student.

• Statement Breakdown 2:
  • Key Phrase: greatest ... occurred in
  • Meaning: We are looking for the largest calculated total appropriations among the given years.
  • Relation to Chart: We must compare the calculated totals for the three specified years.

• What is needed: Which year (out of 2003, 2005, and 2007) had the greatest total appropriations.

Solution:

• Condensed Solution Implementation:
  For each year, calculate total appropriations by multiplying enrollment (thousands of students) by appropriations per student, then compare the three totals.
• Necessary Data points:
  2003: 530 thousand students, $1,600 per student. 2005: 550 thousand students, $1,400 per student. 2007: 570 thousand students, $1,400 per student.
• Calculations Estimations:
  2003: \(530 \times \$1,600 = \$848,000\) thousand. 2005: \(550 \times \$1,400 = \$770,000\) thousand. 2007: \(570 \times \$1,400 = \$798,000\) thousand.
• Comparison to Answer Choices:
  The largest is $848,000 thousand (2003); so 2003 is the answer.

FINAL ANSWER Blank 2: 2003

Summary

In both questions, we needed to calculate the total appropriations for each year (enrollment times appropriations per student) because the chart did not directly provide this number. Then, by comparing those totals, we identified either the least or greatest value for each set of years.

Question Independence Analysis

Each blank refers to a different set of years and a different comparison (least vs. greatest). The calculation steps are the same, but the answers to the two blanks do not depend on each other; they are independent.
