The Sea Wharf Restaurant would like to determine the best way to
allocate a monthly advertising budget of $1,000 between newspaper
advertising and radio advertising. Management decided that at least
25% of the budget must be spent on each type of media and that the
amount of money spent on local newspaper advertising must be at
least two and a half times the amount spent on radio advertising. A
marketing consultant developed an index that measures audience
exposure per dollar of advertising on a scale from 0 to 100, with
higher values implying greater audience exposure. If the value of
the index for local newspaper advertising is 50 and the value of
the index for spot radio advertising is 80, how should the
restaurant allocate its advertising budget to maximize the value of
total audience exposure?
(a) |
Formulate a linear programming model that can be used to
determine how the restaurant should allocate its advertising budget
in order to maximize the value of total audience exposure. If the
constant is "1" it must be entered in the box. If your answer is
zero enter “0”. |
