Answer:
Given that,
Durable Goods = $1,250
Non-durable Goods = $2,130
Services = $9,000 
Fixed Investment = $1,800
Changes to Business Inventory = $135
Investment in Stocks & Bonds = $15,500
Federal Government Purchases = $1,800
State/Local Government Purchases = $1,700
Transfer Payments = $675
Exports from the United States = $2,100
Imports into the United States = $2,400
(a) Consumption, C = durable goods + non-durable goods + services
                                 = $1,250 + $2,130 + $9,000 
                                 = $12,380
(b) Private investment, I = Fixed investment + change in inventory + Investment in stocks/bonds
                                        = $1,800 + $135 + $15,500
                                        = $17,435
(c) Government spending, G = Federal government purchase + state/local government purchase
                                                = $1,800 + $1,700
                                                = $3,500
(d) Net exports = Exports - Imports
                          = $2,100 - $2,400
                          = -($300)
GDP = C + I + G + NX
         = $12,380 + $17,435 + $3,500 + (-$300)
         = $33,015
