Assume that the goods are consumed on a one-to-one basis and one good is worthless without the other. The price of good A and B are both 3 birr. A. How many units of good A&B will the consumer buy? B. If the price of good A increases to birr 6, how many he/she buy of each? C.vWhat type of preferences does consumption of the two goods represent? What is the shape of the indifference curve for this type of preference?
