Harris Segal, marketing director for North-Central Power and Light, is about to begin an advertising campaign promoting energy conservation. In trying to budget between television and newspaper advertisements, he sets the following goals in order of importance:
1. The total advertising budget of $120,000 should not be exceeded.
2. There should be a mix of TV and newspaper ads, with at least 10 TV spots (costing $5,000 each) and at least 20 newspaper ads (costing $2,000 each).
3. The total number of people to read or hear the advertisements should be at least 9 million.
Each television spot reaches approximately 30,000 people. A newspaper advertisement is read by about 150,000 persons. Formulate Segal's goal programming problem to find out how many of each type of ad to place.
