Consider the following utility function for a representative consumer: U (x1, x2) = x1x2.Suppose that x1costs 1 TL a unit and x2costs 2 TL a unit. This individual has 12 TL to spend on x1and x2.

1. Assume a representative consumer buying 10 burgers per week, and his marginal utility of a burger is 15. The price of a burger is 5 TL. He also consumes 10 sandwiches per week, and his marginal utility of a sandwich is 30. Is he maximizing utility at his current consumption basket? If not, should he buy more sandwiches each week, or fewer?
