- The demand for a commodity generally decreases as the price is raised. Suppose that the demand for oil (per capita per year) is D(p)=1000//p barreis, where p is the price per barrel in dollars. Find the demand when p=55. Estimate the decrease in demand if p rises to 56 and the increase in demand if p is decreased to 54. The demand D(55)= The decrease in demand =? barrels. The increase in demand =? barrels.A large company in the communication and publishing industry hs quantified the relationship between the price of one of its products and the demand for this product as Price = 160 -0.01 xDemand for an annual printing of this particular product. The foxed costs per year (ie. per printing) = $4T 000 and the variable cost per unit = $35. What is the maximum profit that can be achieved? What is the unit price at this point of optimal demand? Demand is not expected to be more than 7,000 units per year. The maximum profit that can be achieved is S. (Round to the nearest dolar.) The unit price at the point of optimal demand is S per unit (Round to the nearest cent)QUESTION 7 28 C 24 20 16 12 8 4 0 4 8 O a) 1 Ob)-3 Oc)-11 Od) 17/3 O e) 2/11 Of)-2/21 Og) - 3/15.5 Oh)-3/1.5 12 16 20 E 07.

- Subpart to be solved 1. Consider the following: If the price per unit of good A is P200 quantity purchased isvalued at 1,500 units. If price changes (increase or decrease) by P1, quantity demandedchanges (decreases or increases) by 4 units.A. Determine the demand function expressed as a price function. B. Set up a demand schedule for this function and determine the price elasticity ofdemand at various P and Qd combinations using point-price elasticity formula.(Make sure that all elasticity concepts are found on the same demand curve.) C. Determine the TR and MR functions.D. Graph the demand curve and the TR curve (TR curve just below the demand curve)E. At what P and Qd combination will TR be maximum?Kk177. Suppose the market demand function is given as;Qd = 5I + 10P_1 − 0.4P^2where I is income in $1000 and P1 is price of a related good.(a) What is the relation between these two goods?(b) Calculate the income, cross price, and own price elasticities of demand if I = $50,000, P1 = $10 and P = $20.(c) At what price is demand unit elastic if I = $50,000 and P1 = $10?P & A Ch 05 Q10 Consider public policy aimed at smoking. Studies indicate that the price elasticity of demand for cigarettes is about 0.2. If a pack of cigarettes currently costs $5 and the government wants to reduce smoking by 10%, it should increase the price by ? %. If the government permanently increases the price of cigarettes, the effect on smoking 1 year from now will be ( larger / smaller ) than the effect 3 months from now. Studies also find that teenagers have a higher price elasticity of demand than do adults. Which of the following statements are consistent with this result? Check all that apply. Adults are more likely to be addicted to cigarettes. Teenagers do not have as much income as adults, so they are more price sensitive. It is legal for adults to consume alcohol, so many choose to spend their money on that good rather than cigarettes.
- Suppose the average age of Stanford Alumni increased at the same time the smaller stadium was built and the income elasticity of ticket sales is .5 Group of answer choices Tickets are an inferior good. If income increases with age, it is more likely the smaller stadium will increase total revenue because any increase in ticket revenue from the increase in prices will be reinforced by an increase in ticket sales from the higher income of Stanford Alumni. If income increases with age, it is less likely the smaller stadium will increase total revenue because any increase in ticket revenue from the increase in prices will be offset by a decrease in ticket sales from the higher income of Stanford Alumni.Suppose you are the manager of the state transport company and your finance officer has just told you that the company is making losses .To reverse the losses been made by STC,your decide to cut transport service to certain destination but your board of directors do not want you to cut service,which means that you cannot cut costs.Your only hope is to increase revenue.

- Over the range from $12 to $14, Qd goes from 30 to 24. Using this range of prices and quantities, you should calculate the coefficient of price elasticity of demand. In the box labeled E1, the coefficient of price elasticity of demand is: 2 6 1.36 1.44 In box E2, you would interpret the coefficient calculated in the previous question. Therefore, you would characterize this range as: Elastic Unit Elastic Inelastic None of the AboveThe daily demand for Invigorated PED shoes is estimated to be Q = 100– 3P, + 4P, – .01M + 24, where A, represents the amount of advertising spent on shoes (X), P, is the price of good X, P, is the price of good Y, and M is average income. Suppose good X sells at Rs.50 a pair, good Y sells at Rs.70, the company utilizes 100 units of advertising, and average consumer income is Rs.40,000. Calculate and interpret 1. Own Price Elasticity of demand 2. Cross Price Elasticity of demand 3. Income Elasticity of demand. 4. Are goods X and Y substitutes or complements? 5. Is good X a normal or an inferior good?A store that sells maize meal discovers that when the price of 1kg maize meal is R24 per kilogram, the quantity demanded is 306 kgs per week. When the price decreases to R21 per kg, then the sales increase to 340kgs per week. Use this information to answer questions 3.1.1 and 3.1.2 below: 3.1.1. Determine the price elasticity of maize meal using the arc method (5) 3.1.2 Discuss the relationship between the price elasticity of maize meal and the total revenue the store received from the sales.
