Explanation:
A. Since a Canadian employee can make two cars or 30 cars of wheat each year, a car's opportunity costs 15 cars of wheat. In the same way, the cost of a wheat bushel is one quarter of a vehicle. The cost of the opportunity is the mutual costs.
B. When all 10 million workers are producing two cars each, a total of 20 million cars is produced, which means that the production opportunities are intercepted vertically. For every 10 million employees produce 30 bushels of wheat each, the horizontal interception between output possibilities is a total of 300 million bushels. Although the trade is still the same between cars and wheat, development incentives are a straight line.
C. When Canada continues to import 10 million vehicles in Canada by the US, It will have to manufacture a minimum of 20 million cars. Thus Canada produces the production opportunities at the vertical dispatch. However Canada will be able to consume 200 million bushels of wheat and 10 million cars if its vehicles are 20 bushels of wheat per car. The offer should be accepted by Canada.
