Answer:
c. increasing; $62.5
Explanation:
The computation is shown below;
As we know that
Multiplier = 1 ÷ 1 - MPC
= 1 ÷ 1 - 0.75
= 1 ÷ 0.25
= 4
Now if the equilibrium GDP is $250 billion less than the expected level of GDP
So, the government spending would be increased by
= $250 billion ÷ 4
= $62.5
Hence, the correct option is c.
