Answer:
a) $100 b) $925 c) $75 d) $25 e) $100
Explanation:
GDP = $1,000
Government purchases = $200
Consumption = $700
Budget surplus = $25
We use the formula
GDP = consumption + Investment + government spending.
zero imports and exports because it's a closed economy.
1) Investment = GDP - ( consumption + government spending)
I = $1000 - $900
Investment = $100
National savings (a.k.a. investment) = public savings + private savings = $100
Public savings = Budget surplus = $25
Private savings = National savings - Public savings
Private savings = $100 - $25 = $75
budget balance = Taxes - expenditure
$25 =Taxes - ($700 + $200) = $925
