Formulate the situation as a system of linear equations. Be sure to state clearly the meaning of each variable. Solve using the Gauss-Jordan method. State your final answer in terms of the original question. (If the system is inconsistent, answer INCONSISTENT. If the system is dependent, parametrize the solutions in terms of the parameters u and v.) A large commercial farm needs 37,000 pounds of potash, 70,500 pounds of nitrogen, and 26,500 pounds of phosphoric acid. Three brands of fertilizer, Grow Rite, MiracleMix, and GreatGreen, are available and contain the amounts of potash, nitrogen, and phosphoric acid per truckload listed in the table. How many truckloads of each brand should be used to provide the required potash, nitrogen, and phosphoric acid? X1 = truckloads of Grow Rite truckloads of Miracle Mix X3 = truckloads of Great Green Grow Rite MiracleMix GreatGreen (Pounds per truckload) Potash Nitrogen Phosphoric acid 400 600 700 500 1000 400 1600 500 300 Additional Materials eBook
