3. In a closed economy, national savings equals investment

Explanation:

For a closed economy, the formula for calculating GDP = C + I + G

Where C - Consumption

I - investment

G - Government Spending

To find investment ,

750 = 300 + I + 400

I = $ 50 million

National savings = private saving + Government saving

Private saving = Y − T − C

750 - 300 - 250 = $200 million

Public savings = T - G

250 - 400 = $-150 million

National savings = $200 - $ 150 million = $ 50 million

Nb - All numerical values are in $ millions
