A movement along the demand curve, represented by points A and B, is shown in the diagram to the right. Point A (30, 70) is the initial point, and point B (40, 60) is the point after the price change. The textbook provides two methods for computing price elasticity of demand. Using the information above, compute the price elasticity of demand using each of these methods. (Enter your responses rounded to two decimal places and include a minus sign if necessary.) Using the initial values as a base, the elasticity of demand is C...

QUESTION 2 Replicas of popular mid-century furniture and homeware can be highly sought after by interior designers. Suppose a company sold 1000 replica Eames chairs for a price of $600 each. However, when they set the price at $750, they only sold 750. Which of the following statements are true: The point price elasticity of demand for replica Eames chairs at a price of $600 is unit elastic. At a price of $600 per chair, a 1% increase in the price of replica Eames chairs would lead to a 1% decrease in the quantity of chairs sold. The point price elasticity of demand for replica Eames chairs at a price of $600 is 0.0239 (to four decimal places). The point price elasticity of demand for replica Eames chairs at a price of $600 is 0.02 (to two decimal places).

The demand for Widgets (QX) is a function of the price of widgets (PX), the price of woozles (PY), and per capita income (1): QX = 1950 - 10 PX + 5 PY-0.11 Currently, PX = 25, PY = 10, and 1 = 15,000. (a) Calculate the elasticity of demand for widgets with respect to its own I price, the price of woozles, and income. (b) Over what range of prices is the demand for widgets elastic? (c) If the cost per widget is 10 and the manufacturer behaves as a monopolist, how many widgets will be sold and at what price: (d) By how much must the price of widgets change if there is a 1% decrease in per capita income and the goal is to keep QX constant.
