Answer: $85 Billion
Step-by-step explanation:
Given that,
Personal consumption expenditures in a specific year = $50 billion
Purchases of stocks and bonds = $30 billion
Net exports = (- $10 billion)
Government purchases = $20 billion
Sales of secondhand items = $8 billion
Gross investment = $25 billion
From the above information, expenditure method is more suitable.
GDP = Personal consumption expenditures + Gross investment + Government purchases + Net exports
= $50 + $25 + $20 - $10
= $85 Billion
