The Spanish Club is selling plates of food as a fundraiser. A plate with 2 tacos, 2 cheese enchiladas, and 1 tamale costs $8.50. A plate with 3 tacos, 2 cheese enchiladas, and 2 tamales costs $13.00. A plate with 1 taco, 3 cheese enchiladas, and 2 tamales costs $11.25. If x represents the costs of a taco, y represents the cost of an enchilada, and z represents the costs of a tamale, which formulated system of three equations in three variables correctly represents the cost for each taco, enchilada, and tamale?

x + 2y + 2z = 8.50
2x + 3y + 2z = 13.00
3x + 2y + z = 11.25

2x + 2y + z = 8.50
3x + 2y + 2z = 13.00
x + 3y + 2z = 11.25

8.50x + 13.00y + 11.25z = 1
6x + 7y + 5z = 18
x + y + z = 32.75

2x + 2y + z = 11.25
3x + 2y + 2z = 8.50
x + 3y + 2z = 13.00
