document.write( "A farmer can buy two types of plant food, mix A and mix B. Each cubic yard of mix A contains 24 pounds of phosphoric acid, 14 pounds of nitrogen, and 14 pounds of potash. Each cubic yard of mix B contains 12 pounds of phosphoric acid, 16 pounds of nitrogen, and 35 pounds of potash. The minimum monthly requirements are 720 pounds of phosphoric acid, 560 pounds of nitrogen , and 700 pounds of potash. If x is the number of cubic yards of mix A used and y is the number of cubic yards of mix B used, write a system of linear inequalities that indicates appropriate restraints on x and y. Find the set of feasible solutions graphically for the amounts of mix A and mix B that can be used.\r
