All right, so in this question, we're talking about different opportunity costs, basically.
00:05
So, we know that american workers can produce five cars per year or 10 tons of grain.
00:18
We know that japanese workers can produce 15 cars per year or five tons of grain.
00:35
I'm sorry, this should be on the outside here.
00:41
All right.
00:41
So now, which has the absolute advantage in producing both? so absolute advantage is just the ability to produce more than your competitor.
00:54
That's all.
00:55
So when it comes to cars, the japanese have the absolute advantage.
01:01
When it comes to grain, the u .s.
01:05
Has absolute advantage.
01:08
All right.
01:09
So now what's the opportunity cost of producing a car for the u .s.? so for the u .s., to produce a car, you need to give up a certain amount of grain, basically.
01:26
10 tons grain.
01:30
So basically all i'm doing here by dividing these is divide this by five to get one car per year.
01:38
The ratio of that is two tons of grain.
01:45
So basically all that's telling us is that to produce one car, it requires two tons of grain.
01:51
Now for producing a ton of grain, it's going to be the opposite.
01:58
10 tons of grain or five cars.
02:04
You divide that by 10, you get one ton grain is 0 .5 cars.
02:12
So now we'll do the same thing for the japanese.
02:18
So 15 cars or 5 tons of grain.
02:25
Now we divide this one way, divide by 15 to get the price of making one car, right? so 5 divided by 15 is your 0 .33 tons grain...
