Answer:
Wrexington's government purchases in 2008 were $1100
Explanation:
GDP of an economy is measured as:
GDP = C + I + G + (X-M)
Where C is consumption, I is investment, G government purchases and X are exports and M imports. So if we simplify for G we have
GDP = C + I + G + (X-M)
GDP -C - I - (X-M ) = G
G= GDP -C - I - (X-M ) = 5000-3000-1100-(400-600)
Replacing values gives us:
G= 900-(-200) = 1100
