Suppose Mary consumes jam sandwiches. Each sandwich contains 2 slices of bread and 3 teaspoons of jam. So the only two goods Mary buys are bread (x,) and jam (x;). a) (5 points) Write down her utility function. b) (5 points) Draw an indifference map for this utility function. Make sure to clearly label any important features of this map. c) (5 points) Suppose the consumer has a budget / and faces prices pb (for bread) and p; (for jam). Find the optimal consumption bundle (x*, x*)
