The Westchester Chamber of Commerce periodically sponsors public service seminars and programs. Currently, promotional plans are under way for this year's program. Advertising alternatives include television, radio, and newspaper. Audience estimates, costs, and maximum media usage limitations are as shown:

To ensure a balanced use of advertising media, radio advertisements must not exceed 50% of the total number of advertisements authorized. In addition, television should account for at least 10% of the total number of advertisements authorized.

Audience per advertisement = tv-100,000 radio- 18,000 newspaper-40,000

Cost per advertisement= tv-2000 radio-300 newspaper-600

Maximum Media Usage= tv-10 radio-20 newspaper- 10

If the promotional budget is limited to $18,200, how many commercial messages should be run on each medium to maximize total audience contact? What is the allocation of the budget among the three media?

1. What is the total audience reached?
2. By how much would audience contact increase if an extra $100 were allocated to the promotional budget?

I have the spreadsheet from a prior answered question but I do not know which numbers go in the chart and the answers to the two questions above. That spreadsheet is sort of confusing.
