Answer:
To determine the number of ads of each type that should be used to reach as many people as possible while adhering to the given constraints, we can use linear programming. The objective function is to maximize the number of people reached, subject to the constraints that at least 10 ads of each type must be used and the number of radio ads must be at least as great as the number of television ads.We can represent the problem with the following mathematical model:Maximize:
3000r + 7000t
Subject to:
r >= 10
t >= 10
r >= t
