Fertilizer is sold in bags labelled with three numbers that indicate the amount of nitrogen (N), phosphoric acid (P205), and potash (K₂O) present. A bag of Vigoro Ultra Turf has the numbers "29-3-4," which means that 100 pounds of this fertilizer contains 29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds of potash. A bag of Parker's Premium Starter has 18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash per 100 pounds. (See the discussion at the start of the section.) Determine the amount of each type required to yield a mixture containing the given amounts of nitrogen, phosphoric acid, and potash. 130 pounds of nitrogen, 106 pounds of phosphoric acid, and 32 pounds of potash.
