(Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?
For each of the determinants of demand in Equation 2.1, identify an example illustrating the effect on the demand for hybrid gasoline-electric vehicles such as the Toyota Prius. Then do the same for each of the determinants of supply in Equation 2.2. In each instance, would equilibrium market price increase or decrease? Consider substitutes such as plug-in hybrids, the Nissan Leaf and Chevy Volt, and complements such as gasoline and lithium ion laptop computer batteries.

Suppose the demand function for product X is estimated by the equation: QDX= -2PX + 0,5PY - 0,2PZ + 1,2I. In there:QDX is the quantity demanded of product XPX is the price of product XPY is the price of product YPZ is the price of product ZI is the average income of consumersa/ Please make an argument to determine the relationship between two products X and Y, X and Z.b/ Please make an argument to determine whether product X is an ordinary good or a low-end good
suppose the demand and supply functions for an item are givem by QX = 50-2P and QX= 10+3P a, represent the above function graphically b, find the equilibrium price and quantity
The demand curve is positively sloped because there is a positive relationship between the dependent variable quantity and independent variable price.
The demand equation for a firm’s product has been estimated as Ln Qx = 7.3 – 2 Ln Px + 0.5 Ln I + 0.25 Ln Py - 1.5 Ln Pz, where Qx represents unit sales of brand X, Px is the price of brand X, I is per-capita income, Py is the price of brand Y, and Pz is the price of brand Z. (A)Write this demand equation in its multiplicative form. (B) What is the price elasticity of demand for brand X? is demand price elastic or inelastic? (C)What is the income elasticity of demand for brand X? What type of good is brand X?

The table below shows the quantity of gasoline supplied by producers (Qs) and quantity of gasoline demanded by consumers (Qd) given certain price levels (P). 1. . Derive the Qd and Qs functions assuming that both variables are linearly related to price of gasoline. 2. Give the economic meaning of the slope of Qs and Qd functions.
The demand for brownie dishes is q(p)=361,201-(p+1)^2 where q is the number of dishes they can sell each month at a price of p cents. Use this function to determine a) the number of dishes they can sell each month if the price is 50 cents, b)the number of dishes they can unload each month if they give them away, and c)the lowest price at which they will be unable to sell any dishes
The demand function for a truckload of firewood for college students in a small town is Qc = 400-p. It is sometimes convenient to rewrite a demand function with price on the left side. We refer to such a relationship as the inverse demand function. Therefore, the inverse dimand function for college student is p = 400 - Qc. The demand function for other town residents is Qr = 400 -2p. What is the inverse demand function for other town residents? At a price of $300,. will college students buy any firewood? What about town residents? At what price is the quantity demanded by other town residents zero? Draw the total demand curve, which sums the demand curves for college students and other residents?
Upon graduating from UT this May, you take on a management position working at UtMax theater. You will consider the utility of seeing performance over 1 month, and suppose that at a regular price of $$$ per ticket (my assigned ticket price is 145), customers will see no performance, however with the price reduced by $5, customers will see one performance per month and when reduced by $10, customers will see two performances. As long as the number performances, x, is small, your demand function for performance can be modeled by p=D(x). Write down your demand function.
