Agripro Fertilizer Sdn. Bhd. produces three grades of commercial fertilizers. A 100-lb bag of grade-A fertilizer contains 18 lb of nitrogen, 4 lb of phosphate, and 5 lb of potassium. A 100-lb bag of grade-B fertilizer contains 20 lb of nitrogen and 4 lb each of phosphate and potassium. A 100-lb bag of grade-C fertilizer contains 24 lb of nitrogen, 3 lb of phosphate, and 6 lb of potassium. There are 26400 lb of nitrogen, 4900 lb of phosphate, and 6200 lb of potassium available. By letting the number of 100-lb bags of grade-A, grade-B, and grade-C be x, y, and z respectively, form a system of linear equations to represent the situation above. (i) (ii) Using Gaussian Elimination method, find the number of 100-lb bags of
