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

Constraint	Television	Radio	Online
Audience per Advertisement	100000	18000	40000
Cost per Advertisement	1400	190	600
Maximum Media Usage	10	10	20

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.

1. If the promotional budget is limited to $20,700, 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? If required, round your answers to the nearest dollar.

Let T = number of television spot advertisements R = number of radio advertisements O = number of online advertisements

	Budget ($)

O=
	Total Budget= $

What is the maximum total audience that would be reached? Round your answer to the nearest whole number.

2. By how much would audience contact increase if an extra $100 were allocated to the promotional budget? Round your answer to the nearest whole number.

Problem 4-03 (Algorithmic) The employee credit union at State University is planning the allocation of funds for the coming year. The credit union makes four types of loans to its members. In addition, the credit union invests in risk-free securities to stabilize income. The various revenue-producing investments together with annual rates of return are as follows:

Type of Loan/Investment	Annual Rate of Return (%)
Automobile Loans	8
Furniture Loans	12
Other Secured Loans	14
Signature Loans	13
Risk-Free Securities	9

• Risk-free securities may not exceed 30% of the total funds available for investment.
