Answer:
Nominal GDP = $500
Real GDP = $400
Step-by-step explanation:
Gross domestic product is the sum of all final goods and services produced in an economy within a given period which is usually a year.
Nominal GDP is GDP calculated using current year prices.
Real GDP is GDP calculated using base year prices.
Nominal GDP = (100×$3)+(50×$4) = $500
Real GDP = (100 × $1.5) + (50×$5) = $400
