Final answer:
To find the value of exports, subtract total consumption, investment, government purchases, and imports from GDP. In this case, Talikastan's exports in 2015 were -$900.
Step-by-step explanation:
GDP, or Gross Domestic Product, is the total value of all final goods and services produced in a country during a specific period of time.
It is calculated by adding up consumption, investment, government spending, and the difference between exports and imports.
In this scenario, the given information is: consumption = $5300, GDP = $8800, government purchases = $1800, imports = $600, and investment = $2000.
To find the value of exports, we can rearrange the formula: exports = GDP - (consumption + investment + government purchases + imports).
Plugging in the given values, exports = $8800 - ($5300 + $2000 + $1800 + $600) = $8800 - $9700 = -$900.
Therefore, Talikastan's exports in 2015 were -$900.
