Anаlyze the fоllоwing bаsed оn the concepts leаrned in Asing the Right Questions: The following is a memo from the marketing director of Lamfonz Pet Stores, which operates thirty pet stores worldwide. “Five years ago, our competitor, Fish Emporium, started advertising in Exotic Pets Monthly magazine. Their sales overall have seen a steady increase of 3-to-5 percent per year since then. In fact, the Fish Emporium store in Gulf City saw even more remarkable gains, becoming the most visited pet store in the United States last year. Meanwhile, our two Lamfonz stores in Gulf City have seen sales steadily decline during the same period.

If we do so, we will be sure to reverse this recent trend of declining sales and start making a profit again.
