The Gleaming Company has just developed a new dishwashing liquid and is preparing for a national television promotional campaign. The firm has decided to schedule a series of 1-minute commercials during the peak homemaker audience viewing hours of 1pm to 5pm. To reach the widest possible audience, Gleaming wants to schedule one commercial on each of four networks and to have one commercial appear during each of the four 1-hour time blocks. The exposure ratings for each hour, which represent the number of viewers per $1,000 spent, are presented in the following table. Which network should be scheduled each hour to provide the maximum audience exposure?
