The following appeared in a memo from the marketing director of Top Dog Pet Stores.

"Five years ago, Fish Emporium started advertising in the magazine

Exotic Pets Monthly. Their stores saw sales increase by 15 percent. The three Fish Emporium stores in Gulf City saw an even greater increase than that. Because Top Dog has some of its largest stores in Gulf City, it seems clear that we should start placing our own ads in

Exotic Pets Monthly. If we do so, we will be sure to reverse the recent trend of declining sales and start making a profit again."
