A candidate for mayor in a small town has allocated

$40,000 for last-minute advertising in the days pre-

ceding the election. Two types of ads will be used:

radio and television. Each radio ad costs $200 and

reaches an estimated 3,000 people. Each television

ad costs $500 and reaches an estimated 7,000 people.

In planning the advertising campaign, the campaign

manager would like to reach as many people

as possible, but she has stipulated that at least 10 ads

of each type must be used. Also, the number of radio

ads must be at least as great as the number of television

ads. How many ads of each type should be

used? How many people will this reach?
