Andy, who loves to cook, makes apple cobbler for his family. the recipe (serves 6) calls for 3 1/4 pounds of apples, 4 3/4 cups of flour,1/7 cup of margarine, 3 5/8 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?
