Homework Help: Microeconomics

Posted by Trisha on Friday, June 17, 2005 at 8:48am.

This is due Monday. I am not sure I am doing it correctly. Can someone help me out?

Assume that Jim is a rational customer who consumes only two goods, apples(A) and nuts(N). Assume also, that his marginal rate of substitution (MRS) of nuts for apples is given by the following formula:
That is, Jim's MRS is simply equal to the ratio of the number of apples consumed to the number of nuts consumed. Jim's income is $200,the price of nuts is $10/lb, and the price of apples is $5/lb.
Calculate the quantities of apples and nuts Jim will consume.

I appreciate the help!

Im a bit confused, could you check to see if you have the problem copied correctly.

You have MRS=MU(a)/MU(n) = N/A
It would make more sense if the equation was: MRS=MU(a)/MU(n) = A/N

In which case, utility is maximized when MRS = slope of the budget constraint which is 2A/N or simply 2.
He consumes 20 apples and 10 nuts.

never mind my first statement; your original formula was (probably) copied correctly.

But the final answer still holds true: Utility is maximized whe the MRS=slope of the busget constraint, which happens at 20A and 10N

mcroeconimics is cool

The problem is copied correctly. thanks for your help!
