- 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. What is Stopdecays average monthly total revenue from the sale of electric toothbrushes before and after the price change determined in part (b)? Is the result in part (c) necessarily desirable? What other factors would have to be taken into consideration?Define the price elasticity of demand. Explain the relationship between total revenue and the price elasticity of demand.Worldwide annual sales of smartphones over two year period were approximately q=-5p+3040 million phones at a selling price of $p per phone. (a) Obtain a formula for the price elasticity of demand E. E=_______ (b) in one of the years the actual selling price was $375 per phone. What was the corresponding price elasticity of demand? E=_______ The demand was going down by about _____% per 1% increase in price at that price level. (c) Use your formula for E to determine the selling price that would’ve resulted in the largest annual revenue. $_______ What would’ve been the resulting annual revenue? (Round your answer to two decimal places) $_____billion

What are the determinants of price elasticity of demand?The demand function for a product is modeled by p = 400 − 2x, 0 ≤ x ≤ 200, where p is the price per unit (in dollars) and x is the number of units. Determine when the demand is elastic and inelastic. (Enter your answer using interval notation. If an answer does not exist, enter DNE.) Determine when the demand is of unit elasticity.
- You own the only pharmacy in the small town of Jackson City, which has 40,000 residents. You would like to get a sense of what the local demand is for seasonal allergy medicine so you can determine how many packages to keep in stock and what price to charge. You conduct a survey of four residents of Jackson City, asking them about the quantity of allergy medicine they would buy each allergy season at various prices. Their responses are shown in the accompanying table. Estimate and graph the demand for the entire town of Jackson City.
