Question: what are the marginal utilities of x1 and x2 given...
What are the marginal utilities of x1 and x2 given the following utility functions, then find the MRS:
U(x1, x2) = 4 x1 + 8 x2
U(x1, x2) = (x1 + 2)(x2 + 1)
Example. To find the marginal utility for x1, think about how a 1 unit increase in x1, keeping all else constant, will change the amount of utility U. Once you have the marginal utilities for both, you can calculate the MRS.
