Advertising Strategy Case Problem- I can't seem to get the numbers right with this problem. Can someone show me step-by-step how to solve this problem?

Duke Motors, Inc., has hired a marketing services firm to develop an advertising strategy for promoting Dukes used car sales. The marketing firm has recommended that Duke use spot announcements on both television and radio as the advertising media for the proposed promotional campaign. Advertising strategy guidelines are expressed as follows:

-Use at least 30 announcements for combined television and radio coverage.

-Do not use more than 25 radio announcements.

-The number of radio announcements cannot be less than the number of television

announcements.

The television station has quoted a cost of $1200 per spot announcement, and the radio station has quoted a cost of $300 per spot announcement. Dukes advertising budget has been set at $25,500. The marketing services firm has rated the various advertising media in terms of audience coverage and recall power of the advertisement. For Dukes media alternatives, the television announcement is rated at 600 and the radio announcement is rated at 200. Dukes president would like to know how many television and how many radio spot announcements should be used to maximize the overall rating of the advertising campaign.

Dukes president believes that the television station will consider running the Duke spot announcement on its highly rated evening news program (at the same cost) if Duke will consider using additional television announcements.

2) The relative merits of each advertising medium.

3) The rating that would be necessary for the news program before it would make sense

to increase the number of television spots.

4) The number of television spots that should be purchased if the news program is rated

highly enough to make increasing the number of television spots advisable.

5) The restrictions placed on the advertising strategy that Duke might want to consider

relaxing or altering.

6) The best use of any possible increase in the advertising budget.

7) Any other information that may help Dukes president make the advertising strategy
