Hi skeeter1!!

The key here is to answer the questions in a proper order so I will
start answering the question 4:

GDP = Personal consumption expenditures + Gross private domestic
investment +
      + Government purchases + U.S. exports - U.S. imports =
    = 475 + 300 + 315 + 249 - 260 = 1079 billion.

The correct answer for this question is B.


Follows the question 2:

NDP = GDP - Consumption of Fixed capital = 1079 - 25 = 1054 billion.

So the correct answer for this question is C.


Question 1

NI (National Income) = NDP - Net foreign factor income earned - 
                  - indirect business taxes =
                = 1054 - 5 - 245 = 804 billion.

PI = NI - social security contributions - corporate income taxes -  
     - undistributed corporate profits + Transfer payments =
   = 804 - 240 - 65 - 60 + 247 = 686 billion.

The correct answer for this question is B.


Question 3
(Here there is a little typo in the problem statement, it must say
"Personal Taxes" where says "Personal Payments").

DI (Disposable Income) = PI - Personal Taxes =
                       = 686 - 45 = 641 billion.

The correct answer is ¿?, there is another typo.
