Answer:
Real GDP is inflation adjusted hence there will be no role of inflation. Real GDP per Capita = Real GDP/ Population
Real GDP in year 1 = Real GDP per capita * population
Real GDP in year 1 = $36,000 * 500 million
Real GDP in year 1 = $18 trillion
Growth rate of Real GDP = 7%
herefore Real GDP in year 2 = x - 18/18 = 7/100
Real GDP in year 2 => 100x - 1800 = 126
Real GDP in year 2 => 100x = 126 + 1800
Real GDP in year 2 => 100x = 1926
Real GDP in year 2 => x = 19.26 trillion
So, Real GDP per capita in year 2 = 19.26 trillion /500 million= 38,520
