Answer:

175 radio ads
10 television ads
595,000 people

Step-by-step explanation:

Radio ads reach 3000/200 = 15 people per dollar.

Television ads reach 7000/500 = 14 people per dollar.

Except for the constraints on the number of TV ads, the best value for the advertising dollar comes from radio ads.

So, we must satisfy the constraint that 10 TV ads are the minimum. Then the remaining 35,000 in advertising budget can be spent on 175 radio ads. The number of people reached by this advertising will be ...

175·3000 +10·7000 = 595,000 . . . people

10 TV ads and 175 radio ads should be used. This campaign will reach 595,000 people.
