Consider a representative consumer in a two goods economy of x and y. The price of good x is 1 TL and the price of y is 3 TL. This consumer is spending all his income at the basket he is currently consuming, and his marginal rate of substitution (MRS) of x for y is 2. Is he at an optimum? If so, show why. If not, explain how he can achieve an optimum point in order to maximize his utility?
