Fertilizer is sold in 100 pound bags labelled with the amount of nitrogen (N), phosphoric acid (P205), and potash (920) present. The mixture of these nutrients varies from one type of fertilizer to the next For exampie, a 100 pound bag of Vigoro Ultra Turf fertilizer contains 29 pounds of nitrogen 3 pounds of phosphoric acid, and 4 pounds of potash, Another type of fertilizer, Parker's Premium Starter, has 18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash per 100 pounds, Determine the amount of each type required to yield a mature containing the 163 pounds of nitrogen, 40 pounds of phosphoric acid, and 26 pounds of potash. The mixture contains pounds of Vigoro, and pounds of Parker's Hint: Let be the amount of 100 pound bags of Vigoro, and the amount of 100 pound bags of Parker Set up and solve the system in the unknowns and and then multiply the solution by 100 to find the number of pounds
