- The Stopdecay Company sells an electric toothbrush for $25. Its sales have averaged 8,000 units per month over the past year. Recently, its closest competitor, Decayfigh ter, reduced the price of its electric toothbrush from $35 to $30. As a result, Stopde cays sales declined by 1,500 units per month. What is the arc cross elasticity of demand between Stopdecays toothbrush and Decayfighters toothbrush? What does this indicate about the relationship between the two products? If Stopdecay knows that the arc price elasticity of demand for its toothbrush is 1.5, what price would Stopdecay have to charge to sell the same number of units as it did before the Decayfighter price cut? Assume that Decayfighter holds the price of its toothbrush constant at $30.

He just got in a shipment of undamaged refrigerators. Al has determined that there are two different types of buyers. One group are high demanders who have a more inelastic demand but tend to be picky about how nice their appliances look (they won't buy a dented one). Other buyers, low demanders, have a relatively more elastic demand, but also don't mind having a refrigerator with some dents. He pays $600 for each refrigerator from his supplier. 3/3 He has calculated that the high and low demander demand functions follows: Low: P = 1,000-0.5QL (QL = 2,000 - 2P) High: P = 1,600 - QH (QH = 1,600 – P) How much profit could Al earn if he sells them as is?

What would his profit then be?When a walk-in clinic spent $5,000 a year on newspaper advertising, it saw 5,000 patients a year.
