An electronics company produces three models of stereo speaker, models A, B, and C, and can deliver them by truck, van, or SUV. A truck holds 2 boxes of model A, 2 boxes of model B, and 3 boxes of model C. A van holds 3 boxes of model A, 4 boxes of model B, and 2 boxes of model C. An SUV holds 5 boxes of model A, 7 boxes of model B, and 1 box of model C. (a) If 27 boxes of model A, 35 boxes of model B, and 16 boxes of model C are to be delivered, how many vehicles of each type should be used so that all operate at full capacity? (b) Model C has been discontinued. If 27 boxes of model A and 35 boxes of modelB are to be delivered, how many vehicles of each type should be used so that all operate at full capacity? -... (a) Write a linear system of equations. Let x represent the number of trucks, y represent the number of vans, and z represent the number of SUVS. Choose the correct answer below. O A. 2x + 3y + 5z = 35 2x + 4y +z = 27 3x + 2y + 7z = 16 O B. 3x + 2y + 5z = 27 2x + 4y - 7z = 35 2x + 3y +z= 16 Yc. 2x + 3y + 5z = 27 2x + 4y + 7z = 35 3x + 2y +z = 16 O D. 2x+ 3y - 5z = 27 2x -y+7z = 35 3x + 2y +z = 16 The electronics company should use 3 truck(s), 2 van(s), and 3 SUV(s). (b) Select the correct choice below and fill in the answer boxes to complete your choice O A. There is one solution. The company should use truck(s), van(s), and SUV(s). O B. There are two solutions. If the company wants to use the most amount of trucks possible, they should use truck(s). van(s), and SUV(s). Otherwise, they should use truck(s), van(s), and SUV(s).
