When we say independent variable, this is the variable in an experiment that is being controlled in order to come up with an answer of a certain problem. In the given scenario above, the independent variable is the sugar consumption. This is the variable that is being controlled in order to know the effects (dependent variable). Hope this helps.
The opportunity cost of a computer in China is 2 cars.
If the two countries specialize and trade, the country that will import is the United States because it has a higher opportunity cost in the production of computers.
The terms of trade would be beneficial to both China and the United States.
If productivity in China doubles, the country that has a comparative advantage in the production of cars is the United States.
<h3>What is comparative advantage?</h3>
Comparative advantage is when a country produces a good at a lower opportunity cost when compared to other countries.
A country should specialise in producing a good for which it has comparative advantage and import goods for which it does not have comparative advantage.
For China:
Opportunity cost in producing computers = 1200 / 200 = 6 cars
Opportunity cost in producing cars = 200 / 1200 = 1/6 computers
For United States:
Opportunity cost in producing computers = 400 / 200 = 2 cars
Opportunity cost in producing cars = 200 / 400 = 1/2 computers
