The first three questions are based on the following case An ad campaign for a new snack chip will be conducted in a limited geographical area and can use TV time, radio time, and Internet ads. Information about each medium is shown below. Medium TV Radio Internet Cost Per Ad 1,000 600 300 # People Reached 20,000 10,000 60,000 Exposure Quality Let T = the number of TV ads Let R = the number of radio ads Let I = the number of Internet ads 35 45 5 The number of Internet ads should be at least one third of all ads. Also, the advertising budget is $18,000. Since this is a special program, we would like to develop a model that will minimize the number of people reached while ensuring a minimum exposure quality of 300. Define the decision variables as follows: 1. What is the objective function? Max 20,000 T + 10,000 R + 80,000 1 Max 35 T +40 R + 51 Min 20,000 T + 10,000 R + 60,000 I Max 20 T + 10 R + 50 I Max 20,000 T + 10,000 R + 60,000 1 2. Which constraint represents the constraint for the minimum exposure quality? 35 T +45 R + 51 = 300 1,000 T + 600 R + 300 1 = 300 20,000 T + 10,000 R + 60,000 1 =T +R O I = (R+T)/2 None of the choices
