6. (10 points) Assume that Joe consumes Food and clothing.

Food

Clothing

(a) Please draw the consumer's indifference curve and show the equilibrium point (Utility maximization point) for the consumer and label it "A".

(b) Assume that the consumer's income increases. Show the increase in income on the graph. Assuming that food is an "inferior" good (increase in income leads to reduced consumption) and clothing is a normal good (increase in income leads to an increase in demand) show where the new equilibrium point (utility maximization point) might be after the increase in income and label it "B".
