Answer:
D. Consumption by $80 billion.
Explanation:
Marginal propensity to Save = 1 / MPS
= 1 / 0.2
= 5
= $20 billion × 5
= $100 billion
= $100 - $20
= $80 billion
Therefore, a $20 billion rise in investment spending will increase consumption by $80 billion.
The investment spending will increase by $120 billion
The first step is to calculate the marginal propensity to spend
= 1/0.2
= 5
= 20 billion × 5
= 100 billion
= 100 billion + 20 billion
= 120 billion
Hence the investment spending will increase by $120 billion
