Answer:
a. $1,500
Step-by-step explanation:
Gross Domestic Product = Consumption + Private Investment + Government Spending + Net Exports ( Exports - Imports)
Consumption: people spend 500 dollars
Private Investment Firm invest 200 planned and 100 unplanned total 300
Goverment spending 200 salaries + 100 goods + 500 welfare = 800
Net export: 400 export - 500 import = -100
GDP = 500 + 300 + 800 - 100 = 1,500
