Final answer:
In this scenario, the United States can produce 10,000 shoes or 40,000 refrigerators, while Mexico can produce 2,000 pairs of shoes or 7,500 refrigerators.
Step-by-step explanation:
In this scenario, the United States can produce 10,000 shoes or 40,000 refrigerators using 40 workers for each product. Mexico also has 40 workers and can produce 2,000 pairs of shoes or 7,500 refrigerators. When both countries specialize in their comparative advantages, their combined production of both goods increases.
