So we get a question about maximizing the utility of pizza and beer. pizza is $ 6 and beer is $ 1.5 , if a budget constraint is $ 18000 maximize the utility.
That part is straightforward, the Utility fucntion is Z * B so zb = U
6z +1.5b = 18000 Marginal rate of substitution is 4b = 1z
Substitute that in you get 6z + 1.5 (4z) = 18000
Z = 1500 and B = 6000 for max utility.
Now, on the second part its harder, cause it says instead the util function is U = zb + 432
How does that affect the amount of each that you want? It either has no effect on the MRS and the amount consumed is the same, or it makes it so that the Marginal rate of substitution is
4(b+ 432) = z + 432 instead, and the problem is worked accordingly. Which one is it?
Third part we just.. didn't know how to do.
It is suppose that the person is offered either a cash gift of $12000 or 8000 more beers. Which would they prefer and why? How do you work it to find which is better? I can work it for the cash gift as that would just change the budget constraint to $30000, but how would you figure out the new amounts consumed if 8000 beers are added? How does that change the marginal rate of substitution or how do you add 8000 beers into the equation to figure how that changes utility?
Please help me. Will give cookies and beer to person with best answer. Also possibly cash gift depending on how much is in my account and if I remember my paypal password.
