In this question, we need to find the opportunity cost of a ton of bananas.
00:07
So the opportunity cost is how much coffee must be given up to produce one unit of banana.
00:45
So we have 50 tons of coffee and 100 tons of banana on our production possibilities frontier.
01:05
So our production possibilities frontier gives us the combination of goods that we can produce with the available resources.
01:17
So this is the maximum number of coffee and bananas we can produce at this point.
01:25
We're going to increase production of bananas to 140 tons.
01:29
So we need to find the difference between these two points.
01:44
So we see the difference would be 40 tons of bananas.
01:53
So how much coffee did we give up to produce this many bananas? so we have initially 50 tons of coffee at the first point.
02:10
And then at the second point, we have 30 tons of coffee.
02:19
So therefore, the difference is 20 tons of coffee.
02:31
So between these two points, we can determine how many bananas, or we can determine the opportunity cost of one ton of bananas.
02:47
So we're going to take the difference between the tons of coffee produced between the two points and the difference between the ton of bananas produced at these two points.
03:08
And we're going to get one -half tons of coffee per one banana.
03:17
So, or one ton of banana...
