The main idea is to say, let's make a decision, or advertise. Give 3 numbers, R,e,c, where R represents the expected benefit of not advertising, E represents the expected gain of advertising, and C represents the cost of advertising. It would be nice to compare the proceeds (advertising revenue-advertising costs) with the benefits of not advertising.
