A brand manager for GolF'al Products must determine how much time to allocate between radio and television advertising during the next month. Market research has provided information on audience exposure, which the manager would like to maJdmize. After reviewing the research, the manager found the following linear optimization model for audience exposure, where x is the number of minutes of radio ads and y is the number of minutes of TV ads. Graph the constraints and identify the feasible region. Then identify each of the oomer points and show how increasing the objective function value identies the optimal solution. Maximize Exposure=340x+81y 400:: + 210mg 24,000 xdlys x20 and Val) Identify the graph of the feasible region. Choose the correct graph below. Identify the vertices of the given feasible region. 3 {Type an ordered pair, using integers or decimals rounded to two decimal places as needed. Use a comma to separate answers as needed.) (Type an ordered pair1 using integers or decimals rounded to two decimal places as needed. Use a comma to separate answers as needed.) The optimal solution is to purchase I: minutes of radio ads and (Rou nd to two decimal places as needed} minutes of '0! ads. which gives the 1" value of the objective function
