A food store makes a 6-1b mixture of walnuts, x, cashews, y, and dates, 2. The cost of walnuts is $1.50 per pound, cashews cost $1.00 per pound, and dates cost $1.50 per pound. The total cost of the mixture is $8.50. The mixture calls for twice as many walnuts as cashews. Which system of equations could be used to find the amount of each ingredient the store used? A. x +y +z = 6 1.50x + 1.00y + 1.50z = 8.50 x = 2y B. x +y +z = 8.50 1.50x + 1.00y + 1.50z = 6 X = 2y C. X + y + z = 6 1.50+1.00y + 1.50z = 8.50 X = 2 + y D. 2 (x + y + 2) = 6 1.50x + 1.00y +1.50z = 8.50 x = 2y
