Answer:
$34 billion
Step-by-step explanation:
Data provided in the question:
Total number of inhabitants of a country = 2 million
1 mean gross income = $20,000 per year
Tax paid by mean individual = $3000 per year
Now,
Mean disposable income
= Mean gross income - Mean tax
= $20,000 - $3,000
= $17,000 per year
Therefore,
Total disposable income per year
= Mean disposable income × Total number of inhabitants of a country
= $17,000 × 2 million
= $34 billion
