Answer: (a) $300 million
(b) 52%
Step-by-step explanation:
Total Government spending in 2010:
= education + welfare and Social Security + health care + defense + payments on debt + other
= $320 + $890 + $270 + $120 + $170 + $240
= $2,010 million
Total Government revenue in 2010:
= income tax + sales tax + corporate tax + social insurance
= $800 + $270 + $300 + $340
= $1,710 million
Hence, Total government spending is greater than the total government revenue.
So,
Littleland need to borrow = $2,010 million - $1,710 million
= $300 million
Littleland need to borrow $300 million to finance its government spending.
Total government debt in 2010:
= Total government debt in 2009 + Increase in debt in 2010
= $3.5 billion + $300 million
= $3.5 billion + $0.3 billion
= $3.8 billion
Littleland's debt to GDP ratio At the end of 2010,


= 0.52
= 52%
