Question 3, Text Questi... 2 correct Part 3 of 5 Points: 0 of 1 Close Suppose that the inverse market demand for silicone replacement tips for Sony earbud headphones is p = PN - 0.1Q, where p is the price per pair of replacement tips, py is the price of a new pair of headphones, and Q is the number of tips per week. Suppose that the inverse supply function of the replacement tips is p = 2 + 0.012 Q. a. The effect of a change in the price of a new pair of headphones on the equilibrium price of replacement tips ( dp/dpN) at the equilibrium is given by 0.107 (Round your answer to three places.) (For the following numerical questions, enter your answer as an integer.) b. If PN = $30, the equilibrium price of replacement tips p is $ 5 and the equilibrium quantity Q is units
