Answer:
$100 billion
Explanation:
Real GDP is currently = $13.55 trillion
Potential real GDP = $14.0 trillion
Gap = $500 billion
Government purchases multiplier = 5.0
Tax multiplier = 4.0
To increase aggregate demand by $500 billion, the required increase in government expenditure is:
= (1 ÷ government purchases multiplier) × change in aggregate demand
= (1 ÷ 5) × $500
= $100 billion
Therefore, the government expenditure need to be increased by $100 billion.
The calculated present value of the annuity is $915,166.70.
Explanation and Solution:
Annuity is a collection of fixed payments made or earned either at the close or at the beginning of any term such that a significant initial payment or receipt may be turned into a set of comparatively minor payments or receipts. An annuity that lasts indefinitely is called perpetuity.
The formula for the present value of the annuity is given by:

Where;
R = annual payment = $75,000
i = interest rate = 5.25%
P = Present value of annuity
n = number of years = 20 years
P = 
P = $915,166.70
