4. The formulation of the following problem and its corresponding augumented coefficient matrix and row reduced matrix are shown below. A zoo veterinarian can purchase animal food of 4 different types, A, B, C, and D. Each food comes in the same size bag, and the number of grams of each of three nutrients in each bag are summarized in the following table. Nutrient a. N₁ N₂ N3 A 5 10 5 5x + 5y +10z+5w=15,000 10x + 5y +30z+10w = 30,000 5x+15y +10z+25w=19,000 B 5 5 15 Food C 10 30 10 For one animal, the veterinarian determines that she needs to combine these bags to get 15,000 g of N₁, 30,000 g of N₂, and 19,000 g of N3. How many bags of each type of food should she order? Let x = no. of bags of Food A, y = no. of bags of Food B, z = no. of bags of Food C, and w= no. of bags of Food D State the general solution using the parameter t.
