Consider a simplified, closed economy with no government. In one year, a mining company extracts iron ore and sells it to a steel manufacturer for $20,000. The steel manufacturer processes the ore into steel beams and sells them to a construction company for $50,000. The construction company then uses the beams to build a house, which it sells to a family for $200,000. Based on these transactions, what is the value of this economy's aggregate output/income (Y)?
