If the price of a cheeseburger is $2 and the price of a bag of french fries is $1, and you have $7 to spend (and you can spend all of it). What is the utility-maximizing combination of cheeseburgers and french fries?

Wouldn't that depend on the utility value of the cheesburger, and the fries? In my case, I hate fries. So for me, three lucious cheesburgers would be it. No fries. Now for my salt loving daughter, she would probably have one cheesburger and the rest in fries.

So what I am suggesting, if one wants to maximize utility, the value of each item has to be included, not just the cost function.

Thanks Bob. I just posted the utilities for both. Can you please help us figure this out? We need it by midnight tonight.
Thanks so much.

Assuming that the utility of a cheeseburger is higher than that of a bag of french fries, the utility-maximizing combination would be to purchase 3 cheeseburgers and 1 bag of french fries. This would give you the highest utility for the given amount of money.

Hi Tracci, I understand that you have assigned utility values to both the cheeseburgers and the fries. However, you haven't provided those values in your question. In order to determine the utility-maximizing combination, we would need to know the specific utility values for each item.

Utility is a way of measuring the satisfaction or value that an individual derives from consuming a particular good or service. It is subjective and varies from person to person. In your case, you mentioned that you hate fries, so the utility of fries for you would be low or even zero. On the other hand, your daughter loves fries, so the utility of fries for her would likely be higher.

To find the utility-maximizing combination, we would need to compare the utility values for both cheeseburgers and fries, given your budget of $7. Let's assume that the utility values for a cheeseburger and a bag of fries, respectively, are U(C) and U(F).

If you have a total of $7 to spend, you could represent the number of cheeseburgers as C and the number of bags of fries as F. The total cost equation would be:

2C + 1F = 7

To maximize utility, we need to compare the marginal utility per dollar spent on each item. In other words, we need to calculate U(C)/2 and U(F)/1 and compare these values.

Without knowing the specific utility values, I cannot give you a definitive answer as to how many cheeseburgers and bags of fries you should buy to maximize utility. You would need to provide the utility values and then calculate the marginal utility per dollar spent on each item. From there, you could allocate your budget to maximize total utility.

I hope this helps clarify the concept of utility-maximizing combination and what information is needed to answer your question.

Sure, I can help with that. Please provide me with the utility values for both the cheeseburgers and fries.
