For lunch, Ada prefers to eat soup and bread in fixed proportions. When she eats X pints of soup, she prefers to eat 2X ounces of bread. If she has X pints of soup and more than 2X ounces of bread, she eats all the soup along with 2X ounces of bread and throws the extra bread away. If she has 2X ounces of bread and more than X ounces of soup (say Y ounces), she eats all the bread along with X ounces of soup and throws the extra soup away. Draw Ada’s indifference curves between soup and bread.
