Answer:
$40 billion
Step-by-step explanation:
Data provided in the question:
Amount spend by government = $4 trillion
Amount raised by Taxes = $3 trillion
Interest rate = 4%
Now,
The bonds to be raised by the government
= Amount spend by government - Amount raised by Taxes
= $4 trillion - $3 trillion
= $1 trillion
or
= $1000 billion
Therefore,
The interest paid by the government each year
= Amount of bonds × Interest rate
= $1000 billion × 0.04
= $40 billion
