An advertising agency is developing an ad campaign for a client using radio and TV advertising. Each minute of TV ads reaches 100,000 people and each minute of radio ads reaches 45,000 people. The client wants to reach at least 1.5 million people and the contract calls for a total of at least 30 minutes of ads. If each minute of TV advertising costs $500 and each minute of radio advertising costs $60, find the number of minutes of each kind of advertising should be purchased to minimize costs. Set up the initial tableau of the dual problem of this standard minimum problem.
