Alan always uses 2oz. of peanut butter and 2oz. of jelly in a PB&J sandwich, and these are the only two commodities he consumes. Assuming he has 2oz. of peanut butter and 2oz. of jelly, how many sandwiches could he make? What if he had 3oz. of peanut butter and 2oz. of jelly? 6oz. of peanut butter and 2oz. of jelly? 2oz. of peanut butter and 4oz. of jelly? Draw his indifference curve for peanut butter (x) and jelly (y) through (2,2). Similarly, draw his indifference curve through (4,4).
