Given the following information about each economy, either calculate the missing variable or determine that it cannot be calculated: a. suppose c = $20.1 billion, i = $3.5 billion, g = $5.2 billion, and nx = $-1 billion. total income is . b. suppose total income is $1.5 trillion, g = $0.8 trillion, and c = $1 trillion. i is . c. suppose total expenditure is $576 billion, c = $445 billion, i = $115 billion, and g = $81 billion. instructions: enter your answer as a whole number. include a negative sign if appropriate. nx is $ billion. exports are . revised jrl 06152012

Explanation:

a. Total income formula is:

Y= C+I+G+NX

Y=20.1+3.5+5.2+(-1)

Y= $27.8 billion

b. In closed economies, income is calculated with this formula:

I=Y-C-G

I= 1.5-1-0.8

I= -$0.3 trillion

In open economies, income cannot be calculated because net exports (NX) data is missing.

c. NX is

NX= 576-445-115-81

NX= -$65 billion

NX is exports minus imports, in this case imports are more than exports. To calculate exports you need imports data.

if i need to borrow money for anything, it would be for something like a house or an apartment but, that depend on the situation.

is this good enough?

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
