Question

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

Answer 1

That answer is actually incorrect just multiply every ingredient by 5/2

Answer 2

Apples : 5 3/4 * 2 1/2 = 23/4 * 5/2 = 115/8 = 14 3/8 lbs

flour : 6 3/4 * 2 1/2 = 27/4 * 5/2 = 135/8 = 16 7/8 cups

margarine : 1/8 * 2 1/2 = 1/8 * 5/2 = 5/16 cups

sugar : 3 5/8 * 2 1/2 = 29/8 * 5/2 = 145/16 = 9 1/16 cups

cinnamon : 2 * 2 1/2 = 2/1 * 5/2 = 10/2 = 5 teaspoons
