- Viking Publishing House observed that in the recent years books on nature conservation and climate change have been very popular. As a matter of fact, Jane Goodall's latest book, "The Book of Hope: A Survival Guide for an Endangered Planet" has been a best-seller and Viking estimates the following demand curve for the book: P = 150 - Q In this equation, P is the price of the book and Q denotes yearly sales in thousands 20,000 books would be expressed as Q = 20 books. In other words, Viking estimates that it incurs a cost of $40 for printing and shipping of each book and pays a $10 royalty to Jane Goodall for each book sold. a. Calculate the profit maximizing OUTPUT and PRICE for this book.

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 $10. Give result accurate to at least 3 decimal places. E(10) = c. At this price ($10): 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.

You have done market research and you know with certainty that your product is a normal good, not an inferior good. The current demand function for your gourmet doggie treats is: QD = 480 -6*P which of course means the equation for your current demand curve is: P = 80 -(1/6)*Q You are opening a new shop in a new part of town, and you know that incomes in that part of town are much lower than incomes are where your shop is now. Which of the following is most likely the demand curve in your new shop? Multiple Choice O P=68- (1/6)*Q P = 102 - (1/6)*Q P=92-(1/6)*Q P = 88 - (1/6)*Qarrow_forward
- A1). The price, p, that a bookstore charges for a special gift edition of a popular trilogy is related to the demand, q, by the equation 100pq + q? = 5,000,000. Suppose the price is currently set at $40. (a). At what rate is the demand currently changing with respect to this price? (Include units) (b). At what rate is the revenue currently changing with respect to this price? (Hint: use the chain rule). (Include units). (c). Suppose the demand is currently increasing at a rate of 50 copies per month. How fast is the price currently changing per month? (again, assume the price is currently $40).Include units.arrow_forward1. The demand function for a certain brand of CD is given by p = -0.01x² - 0.2x + 10 where p is the unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. The supply function is given by p = 0.01x² + 0.2x + 4 where p is the unit price in dollars and x stands for the quantity that will be made available in the market by the supplier, measured in units of a thousand. Determine the producers' surplus if the market price is set at the equilibrium price. (Round your answer to the nearest dollar.)arrow_forward2.

- DINKs are households with "double income, no kids", and such households are invading your neighbourhood. You decide to take advantage of this influx by starting a gourmet take-away food store. Assume that these DINKs in your neighbourhood are your only potential customers.You know that the price elasticity of demand for your food from DINKs is 0.5, and their income elasticity of demand is 1.5.From the standpoint of the quantity that you sell, explain which of the following changes would concern you most.First, the number of DINKs in your neighbourhood falls by 10 percent.Second, the average income of DINKs falls by 5 percent.arrow_forward6:357 A webassign.net In this problem, p is in dollars and q is the number of units. (a) Find the elasticity of the demand function p + 2p + q = 100 at p = 9. (b) How will a price increase affect total revenue? O Since the demand is unitary, there will be no change in the revenue with a price increase. O Since the demand is inelastic, an increase in price will decrease the total revenue. O Since the demand is elastic, an increase in price will decrease the total revenue. Since the demand is inelastic, an increase in price will increase the total revenue. Since the demand is elastic, an increase in price will increase the total revenue. Need Help? Read itarrow_forward
