Consider the following graph:

a)  

Determine the value for the Marginal Rate

of Substitution (MRS) at the point where the individual’s utility is maximized.

b)  

Assume that the individual’s income is

equal to 400 euros/week, what is the price of one meter of housing per week?

c) If the price of housing obtained previously increases to 13 euros/m2 per week, and the individual's income increases to 520 euros/week, how should the feasible space of consumption change? (10 points)
