To identify the years in which there was a budget surplus, we need to compare the revenue and expenditures for each year. A budget surplus occurs when the revenue exceeds the expenditures. Let's go through each year step-by-step:
1. Year 2001:
- Revenue: \[tex]$8 trillion
- Expenditure: \$[/tex]6 trillion
- Since \[tex]$8 trillion > \$[/tex]6 trillion, there is a budget surplus.
2. Year 2002:
- Revenue: \[tex]$5 trillion
- Expenditure: \$[/tex]7 trillion
- Since \[tex]$5 trillion < \$[/tex]7 trillion, there is no budget surplus.
3. Year 2003:
- Revenue: \[tex]$8 trillion
- Expenditure: \$[/tex]10 trillion
- Since \[tex]$8 trillion < \$[/tex]10 trillion, there is no budget surplus.
4. Year 2004:
- Revenue: \[tex]$9 trillion
- Expenditure: \$[/tex]7 trillion
- Since \[tex]$9 trillion > \$[/tex]7 trillion, there is a budget surplus.
5. Year 2005:
- Revenue: \[tex]$15 trillion
- Expenditure: \$[/tex]18 trillion
- Since \[tex]$15 trillion < \$[/tex]18 trillion, there is no budget surplus.
6. Year 2006:
- Revenue: \[tex]$8 trillion
- Expenditure: \$[/tex]10 trillion
- Since \[tex]$8 trillion < \$[/tex]10 trillion, there is no budget surplus.
7. Year 2097:
- Revenue: \[tex]$6 trillion
- Expenditure: \$[/tex]4 trillion
- Since \[tex]$6 trillion > \$[/tex]4 trillion, there is a budget surplus.
8. Year 2008:
- Revenue: \[tex]$2 trillion
- Expenditure: \$[/tex]4 trillion
- Since \[tex]$2 trillion < \$[/tex]4 trillion, there is no budget surplus.
9. Year 2009:
- Revenue: \[tex]$7 trillion
- Expenditure: \$[/tex]4 trillion
- Since \[tex]$7 trillion > \$[/tex]4 trillion, there is a budget surplus.
10. Year 2010:
- Revenue: \[tex]$5 trillion
- Expenditure: \$[/tex]9 trillion
- Since \[tex]$5 trillion < \$[/tex]9 trillion, there is no budget surplus.
Based on our comparison, the years with a budget surplus are:
- 2001
- 2004
- 2097
- 2009
Thus, the years in which there was a budget surplus are 2001, 2004, 2097, and 2009.
