Answer :
To identify the years in which there was a budget surplus, we need to compare the budgeted revenue to the expenditures for each year. A budget surplus occurs when the revenue is greater than the expenditures. Let's go through each year one by one to determine if there was a surplus.
- 2001:
- Revenue: \[tex]$8 trillion - Expenditure: \$[/tex]6 trillion
- Since \[tex]$8 trillion (revenue) > \$[/tex]6 trillion (expenditure), there is a surplus in 2001.
- 2002:
- Revenue: \[tex]$5 trillion - Expenditure: \$[/tex]7 trillion
- Since \[tex]$5 trillion (revenue) < \$[/tex]7 trillion (expenditure), there is no surplus in 2002.
- 2003:
- Revenue: \[tex]$8 trillion - Expenditure: \$[/tex]10 trillion
- Since \[tex]$8 trillion (revenue) < \$[/tex]10 trillion (expenditure), there is no surplus in 2003.
- 2004:
- Revenue: \[tex]$9 trillion - Expenditure: \$[/tex]7 trillion
- Since \[tex]$9 trillion (revenue) > \$[/tex]7 trillion (expenditure), there is a surplus in 2004.
- 2005:
- Revenue: \[tex]$15 trillion - Expenditure: \$[/tex]18 trillion
- Since \[tex]$15 trillion (revenue) < \$[/tex]18 trillion (expenditure), there is no surplus in 2005.
- 2006:
- Revenue: \[tex]$8 trillion - Expenditure: \$[/tex]10 trillion
- Since \[tex]$8 trillion (revenue) < \$[/tex]10 trillion (expenditure), there is no surplus in 2006.
- 2007:
- Revenue: \[tex]$6 trillion - Expenditure: \$[/tex]4 trillion
- Since \[tex]$6 trillion (revenue) > \$[/tex]4 trillion (expenditure), there is a surplus in 2007.
- 2008:
- Revenue: \[tex]$2 trillion - Expenditure: \$[/tex]4 trillion
- Since \[tex]$2 trillion (revenue) < \$[/tex]4 trillion (expenditure), there is no surplus in 2008.
- 2009:
- Revenue: \[tex]$7 trillion - Expenditure: \$[/tex]4 trillion
- Since \[tex]$7 trillion (revenue) > \$[/tex]4 trillion (expenditure), there is a surplus in 2009.
- 2010:
- Revenue: \[tex]$5 trillion - Expenditure: \$[/tex]9 trillion
- Since \[tex]$5 trillion (revenue) < \$[/tex]9 trillion (expenditure), there is no surplus in 2010.
Thus, there were budget surpluses in the years:
- 2001
- 2004
- 2007
- 2009
- 2001:
- Revenue: \[tex]$8 trillion - Expenditure: \$[/tex]6 trillion
- Since \[tex]$8 trillion (revenue) > \$[/tex]6 trillion (expenditure), there is a surplus in 2001.
- 2002:
- Revenue: \[tex]$5 trillion - Expenditure: \$[/tex]7 trillion
- Since \[tex]$5 trillion (revenue) < \$[/tex]7 trillion (expenditure), there is no surplus in 2002.
- 2003:
- Revenue: \[tex]$8 trillion - Expenditure: \$[/tex]10 trillion
- Since \[tex]$8 trillion (revenue) < \$[/tex]10 trillion (expenditure), there is no surplus in 2003.
- 2004:
- Revenue: \[tex]$9 trillion - Expenditure: \$[/tex]7 trillion
- Since \[tex]$9 trillion (revenue) > \$[/tex]7 trillion (expenditure), there is a surplus in 2004.
- 2005:
- Revenue: \[tex]$15 trillion - Expenditure: \$[/tex]18 trillion
- Since \[tex]$15 trillion (revenue) < \$[/tex]18 trillion (expenditure), there is no surplus in 2005.
- 2006:
- Revenue: \[tex]$8 trillion - Expenditure: \$[/tex]10 trillion
- Since \[tex]$8 trillion (revenue) < \$[/tex]10 trillion (expenditure), there is no surplus in 2006.
- 2007:
- Revenue: \[tex]$6 trillion - Expenditure: \$[/tex]4 trillion
- Since \[tex]$6 trillion (revenue) > \$[/tex]4 trillion (expenditure), there is a surplus in 2007.
- 2008:
- Revenue: \[tex]$2 trillion - Expenditure: \$[/tex]4 trillion
- Since \[tex]$2 trillion (revenue) < \$[/tex]4 trillion (expenditure), there is no surplus in 2008.
- 2009:
- Revenue: \[tex]$7 trillion - Expenditure: \$[/tex]4 trillion
- Since \[tex]$7 trillion (revenue) > \$[/tex]4 trillion (expenditure), there is a surplus in 2009.
- 2010:
- Revenue: \[tex]$5 trillion - Expenditure: \$[/tex]9 trillion
- Since \[tex]$5 trillion (revenue) < \$[/tex]9 trillion (expenditure), there is no surplus in 2010.
Thus, there were budget surpluses in the years:
- 2001
- 2004
- 2007
- 2009
