Question

The proliferation of the Internet has given rise to a new method of advertising, called spamming, that essentially is a more cost-effective method of the telephone solicitation method known as cold calling. If a company buys three mailing lists with 2,500, 3,500, and 4,000 email addresses respectively and spams them with promotional material, how many potential customers has it reached?

Answer 1

The number of potential customers reached by the company is the total number of people that received their promotional material

First mailing list - 2,500 addresses
Second mailing list - 3,500 addresses
Third mailing list - 4,000 addresses

Total is, 2500 + 3500 + 4000
= 10,000

Therefore, their promotional materials reached 10,000 potential customers.
