MY NOTES Formulate but do not solve the problem. Lawnco produces three grades of commercial fertilizers. A 100-1b bag of grade A fertilizer contains 16 lb of nitrogen, 6 lb of phosphate, and 7 lb of potassium. A 100-1b 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. How many 100-lb bags of each of the three grades of fertilizers should Lawnco produce if 26,800 lb of nitrogen, 4100 lb of phosphate, and 5900 lb of potassium are available and all the nutrients are used? (Let A, B, and C denote the number of bags of grade A, B, and fertilizer, respectively.) - 26 300 - 4.100 = 6.900 Need Help? Tak to a Tor Submit Answer Practice Anather Verson
