Answer:
The value of GDP is 75
Explanation:
GDP is equal to Consumption + Investment + Government Spending + Net Exports (Exports minus Imports), where total Investment is equal to Fixed Investment plus the Change in Inventories.
The change in GDP will therefore equal the change in Consumption + the change in Investment + the change in Government Spending + the change in Net Exports, where the change in Investment will equal the change in Fixed Investment plus the change in the Change in Inventories.
= Government purchases of goods and services (10) + Consumption Expenditures (70 )+ Exports (5 ) - Imports (12) + Change in Inventories (-7 ) + Construction of new homes and apartments (15 ) - Sales of existing homes and apartments (22 ) + Government payments to retirees (17 ) + Business Fixed Investment (9)
= 75
