Question:

Assume that Roscoe’s Rascals decided to add the pet food line. Two months after it began selling the food, its pet food sales declined dramatically because a competitor across the street started selling the identical food for $22 per bag. Should Roscoe’s Rascals match the price offered by the competitor?
