So here we're talking about consumer choice and we want to maximize, right? and we maximize by buying highest mu over p first, right? marginal utility per over price is like value per dollar, right? when you say marginal utility over price, you're thinking about how much we are getting per dollar.
00:30
So now we have prices, we know the price of oranges is equal to one, we know the price of apples is equal to one, we know the price of bananas is equal to 0 .5.
00:40
Let's start buying.
00:41
So quantity, we have oranges, or sorry, we have mu over p of oranges, we have mu over p for apples, we have mu over p for bananas, dot, dot, dot.
01:01
So for the first one, you see that the highest payoff is for oranges, right? and that costs a dollar.
01:12
So that's $1 spent.
01:15
Now, the second thing we're going to buy is the 14, right? we see there is a 14 here...
