should be spent in the following media: television, radio, magazines, and prize promotion. Each dollar spent on television advertising increases sales $10; both radio and magazine ads result in half that return, and prize promotion returns $20 in sales for each dollar invested. Television advertising cannot exceed half of the total budget, and total radio advertising must be at least 20% of total TV advertising. At least $20,000 must be spent on magazine ads, and no more than $25,000 may be spent on the prize promotion. Management's objective is to maximize the total increase in Quicker's sales volume. Formulate the decision as a linear program and determine the maximum total increase in Quicker’s sales volume.
