Refer to the figure to solve the problem.A linear programing problem has the objective function , which is to be minimized. The following graph shows the feasible set and the straight line of all combinations of x and y for which the cost is $72. Give the linear equation (in standard form) of the line of constant cost c. Then, by inspection, find the vertex of the feasible set that gives the optimal solution.
