Andy, who loves to cook, makes apple cobbler for his family. The recipe (serves 6) calls for 1 1/4 pounds of apples, 3 1/4 cups of flour, 1/5 cup of margarine, 4 3/8 cups of sugar, and 2 teaspoons of cinnamon. Since guests are coming, Andy wants to make a cobbler that will serve 15 (or increase the recipe 2 1/2 times). How much of each ingredient should Andy use?
