In the last part, we saw that Saudi Arabia has a comparative advantage in the production of oil, while the US has a comparative advantage in the production of cars.

(Description)
There are two tables on the slide. The first table labeled Saudi Arabia consists of 2 columns: Quantity of oil (millions of barrels), Quantity of cars (millions). The table consists of 5 rows. The first row: Quantity of oil is, 0 million barrels, Quantity of cars is, 4 million. The second row: Quantity of oil is, 200 million barrels, Quantity of cars is, 3 million. The third row: Quantity of oil is, 400 million barrels, Quantity of cars is, 2 million. The fourth row: Quantity of oil is, 600 million barrels, Quantity of cars is, 1 million. The fifth row: Quantity of oil is, 800 million barrels, Quantity of cars is, 0 million. The second table labeled United States consists of 2 columns: Quantity of oil (millions of barrels), Quantity of cars (millions). The table consists of 5 rows. The first row: Quantity of oil is, 0 million barrels, Quantity of cars is, 10.0 million. The second row: Quantity of oil is, 100 million barrels, Quantity of cars is, 7.5 million. The third row: Quantity of oil is, 200 million barrels, Quantity of cars is, 5.0 million. The fourth row: Quantity of oil is, 300 million barrels, Quantity of cars is, 2.5 million. The fifth row: Quantity of oil is, 400 million barrels, Quantity of cars is, 0 million.

This problem asks you to find the total production for oil and cars assuming each country specialize production for which they have a comparative advantage. We're going to start with oil and look at the production by Saudi Arabia. If Saudi Arabia produces only oil and no cars, they will produce 800 million barrels of oil.
