Formulate a linear programming problem that can be used to solve the following question. A farmer has two fields in which he grows wheat and corn. Because of different conditions, there are differences in the yield of growing these crops in these two fields. The sizes, yields, and costs are shown in the table; 6,960 bushels of wheat and 19,440 bushels of corn are to be grown. Determine a planting plan that will minimize the cost.
