Final answer:
The aggregate supply over one year will be equal to the total amount of goods and services produced by all businesses and industries in that country during that year.
Step-by-step explanation:
If all production takes place within a country's border, the aggregate supply over one year will be equal to the total amount of goods and services produced by all businesses and industries in that country during that year. This includes both the goods and services consumed domestically and those exported to other countries. For example, if a country produces 10 million tons of steel, 1 million cars, and provides 5 million hours of professional services, the aggregate supply for that year would be the sum of these quantities.
