Answer:
$12 billion
Step-by-step explanation:
Data provided in the question:
Required reduction in the consumption = $36 billion
MPC = 0.75
Now,
Total income = [ Required reduction in the consumption ] ÷ MPC
= [ $36 billion ] ÷ 0.75
= $48 billion
Therefore,
The raise in tax = Total income - Required reduction in the consumption
= $48 billion - $36 billion
= $12 billion
