In international trade, if Country A can produce cars more efficiently than Country B, but Country B has a lower opportunity cost in producing textiles, how should both countries engage in trade to benefit from their comparative advantages?

In international trade, countries benefit by focusing on what they can produce most efficiently and trading for what they cannot produce as well. If Country A can make cars more efficiently than Country B, it should specialize in car production. Meanwhile, if Country B has a lower opportunity cost for making textiles, it should focus on producing textiles. By trading cars for textiles, both countries can enjoy more cars and textiles than if they tried to produce both on their own. For example, if Country A produces 10 cars and Country B produces 20 textiles, they can trade a few cars for textiles, allowing both to enjoy a greater variety of goods.
