Question #2 Consider the following demand function for frozen dinners where QD is the quantity of frozen dinners demanded per week, P is the price per frozen dinner, PF is the price per fast food meal, Y is the average yearly consumer income, and A is the number of advertisements for frozen dinners.    Demand Function for Frozen Dinners: QD = 1,000 – 10P + 20PF – 0.01Y + A         Suppose that a frozen dinner sells for $4, a fast food meal sells for $6, average yearly consumer income is $50,000, and that there are 20 advertisements for frozen dinners. Calculate and interpret the income elasticity of demand. Calculate and interpret the cross-price elasticity of demand with respect to fast food meals.

The weekly demand function is given by p+x+4xp = 68, where x is the number of thousands of units demanded weekly and p is in dollars. If the price pis decreasing at a rate of 91 cents per week when the level of demand is 5000 units, which one of the following statements is true? Demand is decreasing at 1330 units per week Demand is decreasing at 1470 units per week Demand is increasing at 1470 units per week O Demand is increasing at 1400 units per week O Demand is decreasing at 1400 units per week

The manager of a bicycle shop has found that, at a price (in Rands) of p(x) = 150 –x/4 per bicycle, x bicycles will be sold . Answer the following:• Find an expression for the total revenue from the sale of x bicycles. (Hint: Revenue = Demand *Price. )• Find the expression for the quantity to be sold q if the demand function demand is given byp = -10q + 3200• What is the number of bicycles x, sold if the price is R40

ABC Manufacturing has determined that the demand function for their heated socks is given by: 6 D(p) = 170 --p². a. Find E(p), the Elasticity of Demand as a function of price, p. E(p) = b. Find the Elasticity of Demand when heated socks are selling at a price of $5. Give result accurate to at least 3 decimal places. E(5) c. At this price ($5): We would say the demand for heated socks is: [Select an answer Based on this, in order to increase revenue we should: [Select an answer d. Use the Elasticity model to determine the price that maximizes revenue. (Round result to 2 decimal places.) P =

Use the Elasticity model to determine the price that maximizes revenue. (Round result to 2 decimal places.) D(p) = = 345- p=

Using regression analysis on data from a field experiment, the demand curve for a product is estimated to be QXd = 1,200 − 3PX − 0.1PZ where Pz = $300.  a. What is the own price elasticity of demand when Px = $140? Is demand elastic or inelastic at this price? What would happen to the firm’s revenue if it decided to charge a price below $140?Instruction: Enter your response rounded to two decimal places. Own price elasticity:    Demand is:           .   If the firm prices below $140, revenue will:              .   b. What is the own price elasticity of demand when Px = $240? Is demand elastic or inelastic at this price? What would happen to the firm’s revenue if it decided to charge a price above $240? Instruction: Enter your response rounded to one decimal place. Own price elasticity:    Demand is:           .   If the firm prices above $240, revenue will:              .   c.

Suppose that the demand curve for a product is given by = 100 – 2 Px+a Py, = £20 is the price of another product, and where a Py %3D where Px = £20, where = 8. a) Calculate the demand for good X in this market at the current price level. How much revenue would the firm make? b) If the firm wishes to increase total revenue, would it need to increase or decrease the current price of good X? c) Calculate the cross-price point elasticity between goods X and Y at the current price level. Are the goods complements or substitutes? Note: The writing is clear and abbreviations are not allowed.
