Prior to 1996, Upjohn Company's hair regrowth product, Rogaine, required a prescription. It retailed for approximately $50 a bottle (2 fl. Oz.) Then in early 1996 Upjohn obtained approval from the Federal Drug Administration to sell Rogaine without a prescription. The retail price was reduced sharply to approximately $30 a bottle. Using the principles of elasticity, draw a demand schedule that justifies Upjohn's decision to cut the price from $50 to $30.
