Hello, here we have two different questions.
00:09
We have question 9.
00:12
And this question we have the production possibilities frontier at which cars on the horizontal axis and boats on the vertical axis.
00:31
And the constant slope is not.
00:36
0 .25.
00:41
So it's something like this.
00:46
So here we have four units, you have also four units and this is the slope.
01:00
The question is what is the opportunity cost of a car for this economy? so when this economy tries to produce one additional car like from here to there it will sacrifice one fourth of boat so the opportunity cost of the car is equal to the slope it's not negative it's positive so the answer is 0 .25 it's equal to the the negative number of this constant slope.
01:53
So the answer is a.
01:59
Okay, and now we answer to the second question.
02:05
Question number 10.
02:08
