Answer :
Answer:The answer is $134billion
Explanation:
Initial increase in spending = $20billion
Marginal propensity to consume = 0.85
To calculate increase in spending, we use the formula for multiplier
K = 1 / 1 - MPC
K = 1 / 1 - 0.85
K = 1/ 0.15
K = 6.66
K = 6.7 approximately
To calculate how much the spending increase
We use the formula
K = change in national income / change in government spending
6.7 = change in national income / $20 billion
We cross multiply
Change in national income = 6.7 × $20billion
Change in national income = 134billion
Therefore the total spending increase by $134billion
