Answer:
The increase in GDP is $250
Step-by-step explanation:
The increase in investment spending = $100
Marginal propensity to consume = 0.6
Now we have to find an increase in the GDP after absorbing the $100.
Therefore, we need to find the multiplier by using the marginal propensity to consume.
Multiplier = 1 / (1-MPC)
Multiplier = 1/( 1- 0.6)
Multiplier = 2.5
The increase in GDP = increase in investment spending × Multiplier
The increase in GDP = 100 × 2.5 = $250
