7(n - p) + 5p
7n - 7p + 5p

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
X^2+4x-12
x^2+6x-2x-12
x(x+6)-2(x+6)
(x-2)(x+6)
So, B is the answer
