Answer:
d. $2,500 worth of goods and services.
Step-by-step explanation:
The national income identity is given by:
GDP = C + I + G + EX − IM.
Market value of all final goods and services produced within the economy was $5,500 => GDP = $5,500
Consumption (C), investment (I), and government purchases (G) added up to $5,000 => C + I + G = $5,000
=> EX - IM = GDP - (C + I + G) = $500
Imports amounted to 80 percent of the value of exports => IM = 0.8EX
=> EX - 0.8 EX = $500
=> EX = $2,500
