Answer:
$400
Step-by-step explanation:
Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year
GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export
Net export = exports – imports
Inventory grew by (200 - 100) $100
$50 of value was created
total gdp = $100 + $250 + 50 = $400
