So for this question, we're given this utility function.
00:04
The two goods are consumed in a fixed proportion.
00:07
So w is equal to one -half g.
00:12
And then we rearrange this.
00:19
The ratio between w and g is 0 .5.
00:23
So at equilibrium, w is equal to 0 .5g.
00:31
We'll put granola bars on the y and water bottles on the x.
00:40
Now we find g in terms of w.
00:48
So we'll see that it would be g is equal to 2w.
01:02
So then we evaluate u as equal to 1.
01:12
So if u is equal to 1, w is equal to 1.
01:35
So then 1 is equal to 1 1 half g.
01:42
Then we can get g...
