Let's go over this question.
00:02
We want to find mary's opportunity cost of one muffin.
00:15
So it would be the amount given up over the amount of whatever we gain from giving up the other good.
00:28
So if we take a look at mary's production possibilities frontier, if she uses all of her resources she can produce four muffins.
00:42
And if she uses all of her resources for cookies, she can produce eight cookies.
00:47
So we have to put muffins on the bottom because that is what we're going to gain.
00:58
So she uses all of her resources for either eight cookies or four muffins.
01:06
So we simplify this just to give up two cookies to get one muffin.
01:17
So the opportunity cost of producing one muffin is two cookies.
01:25
So now we want the opportunity cost for one cookie.
01:30
So our equation is the same.
01:47
So she can make either a total of four muffins using all of her available resources or eight cookies.
01:56
So this time we'll put cookies on the bottom.
01:59
And then we need to simplify this...
