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
The GDP of this country is the sum of outputs of this country multiplied by their prices
(5 x $2) + (10 x $1) + (20 x $1.50) = $10 + $10 + $30 =$50
