This question is about the perfect compliments question in economics.

Ufle for movie tickets, and one for vacations. 6.) Let Charlie have a perfect complements utility function over french bread (F) and butter (B): U = min {2F, B}. a.) Suppose that Charlie wants to achieve a minimum utility level of 100. The price of F is $10, and the price of B is $4. How many units of F and how many units of B would Charlie have to buy? What would his expenditures be? b.) Derive the Uncompensated (Hicksian) Demand Functions for French Bread and Butter. These are the solutions from the expenditure minimization problem. c.) Calculate the price elasticity of demand for butter using the Uncompensated (Hicksian) Demand function you found in part a. Interpret what this elasticity means
