Find the system of equations to model the problem. DO NOT SOLVE THIS SYSTEM.Hurst's Feed & Seed sold to one customer 5 bushels of wheat, 2 of corn, and 3 of rye, for $31.00. To another customer he sold 2 bushels of wheat, 3 of corn, and 5 of rye, for $27.60. To a third customer he sold 3 bushels of wheat, 5 of corn, and 2 of rye for $32.70. What was the price per bushel for each of the different grains?Let x represent the price per bushel for wheat, y the price per bushel for corn, and z the price per bushel for rye.
A. 5x + 2y + 3z = 31.00 2x + 3y - 5z = 27.60 3x + 5y - 2z = 32.70 B. 5x + 2y + 3z = 31.00 2x + 3y + 5z = 27.60 3x + 5y + 2z = 32.70 C. 5x + 2y - 3z = 31.00 2x + 3y - 5z = 27.60 3x + 5y - 2z = 32.70 D. 5x + 2y + 3z = 31.00 2x - 3y + 5z = 27.60 3x + 5y + 2z = 32.70
