• The opportunity cost is the value of the option not chosen when making a decision

Explain the concept of production possibilities frontier.

• It is the graphical representation of the different combinations of goods and services that an economy cannot produce

• It is the graphical representation of the different combinations of goods and services that an economy can produce, given its resource and technology limitations.

• It is the graphical representation of the different combinations of goods and services that an economy chooses to produce

• It is the graphical representation of the different combinations of goods and services that an economy can produce, without resource and technology limitations

What is the circular flow of income in the economy?

What is the impact of technology on the production possibilities frontier?

• Increases the production possibilities frontier by decreasing efficiency in the production of goods and services

• Reduces the production possibilities frontier by limiting the quantity of goods and services that can be produced

• Expands the production possibilities frontier by allowing the production of more goods and services with the same resources.
