The number of retro portable CD players you are prepared to supply to a retail outlet every week is given by the formula
q = 0.2p? + 5p,
where p is the price it offers you. The retail outlet is currently offering you $90 per CD player. If the price it offers
decreases at a rate of $1 per week, how will this affect the number you supply?
The supply will --Select-- v
at a rate of
CD players per week.
The demand equation for a certain brand of pencil is
100y? + 9t2 = 3600
where (y) represents the number (in thousands) of ten-packs demanded each week when the unit price
is $(t). How fast is the quantity demanded increasing when the unit price per ten-pack is $14 and the
selling price is dropping at the rate of $0.15 per ten-pack per week?
Analyze the demand function for Toyotas in problem C4, page 82. Please also read “What is a Symbol” located in the folder with this assignment.
This function is:
QT = 200 -.01PT +.005PM -10PG +.01I +.003A
Where:
QT = quantity purchased
PT = average price of Toyotas
PM = average price of Mazdas
PG = price of gasoline
I = per capita income
A = dollars spent annually on advertising
Characterize this function by circling all in the following list that are applicable:
univariate, bivariate, multivariate, linear, exponential, logarithmic, curvilinear, 1st degree, 3rd degree, additive, multiplicative, linearly homogeneous
What is the numerical value of the partial derivative of the function with respect to the price of gasoline (PG) (be sure to also include the + or – sign. Note: I do not want the symbol for this partial derivative)?
Write the mathematical symbol representing the coefficient of income (I) (the numerical…

- The quantity demanded for the Sony VCR model 37 is 2500 per week when the unit price is $700. For each increase in unit price of $50, the quantity demanded decreases by 250 units. The suppliers will provide 2500 units when the price is $800 per unit, and they will not supply any units for $500 or less. (Note: Define your variables.) A. Algebraically determine the supply equation. (Place in function form.) B. Algebraically determine the demand equation. (Place in function form.) C. Algebraically determine the equilibrium quantity and price. D. At what price does excess supply occur?arrow_forwardAn economist estimates that a market has a demand curve of the form P = 26 - (0.867) Q and a supply curve of the form P = 0.5 + (1.21) Q. (See the curves graphed in the figure below.) Accordingly, she estimates that the equilibrium price ( P e) in the market will be $15.36 (or $15.355561). This means that the amount of the product bought and sold in the market must be ____.arrow_forwardIn the following question(s) you are asked to determine, other things equal, the effects of a given change in a determinant of demand or supply for product X upon (1) the demand (D) for, or supply (S) of, X, (2) the equilibrium price (P) of X and (3) the equilibrium quantity (Q) of X. Refer to the above. An increase in the price of a product that is a close substitute for X will: Group of answer choices a. decrease D, increase P, and decrease Q. b. increase D, increase P, and decrease Q. c. increase D, increase P, and increase Q. d. increase D, decrease P, and increase Q.arrow_forward
- Due to a recession that lowered incomes, the 2008 market prices for last-minute rentals of U.S. beachfront properties were lower than usual. Suppose that the inverse demand function for renting a beachfront property in Ocean City, New Jersey, during the first week of August is Derive the equilibrium price, p, and the quantity, Q", in terms of Y. The equilibrium quantity, Q', ist p=1000-Q+= Y where Y is the median annual income of the people involved in this market, Q is quantity, and p is the rental price. The inverse supply function is Q Y 50 p= Q² = 10arrow_forwardWhat is a relevant example of how a change in the market (including information, preferences, technology, price of alternative goods, regulations, taxes, etc.) has shifted either the supply or demand of a good. How did this change affect the market equilibrium for that good or service? Explain. Next, find a relatively recent news article (within the past year) to support your finding (the news search feature in Google is helpful with this). If you cannot find an article specific to your example, you may find an article about another similar good or service. Talk about the article and its findings, then include the URL.arrow_forwardWe obtain the following demand curve of beef in a market: = 30302.189-4303.602 In (P), where Q is quantity demanded of beef measured in pounds, P is price measured in dollars per pound. We know P = 8.906 and Q=12027.759. Based on this information, if price increases by 1 dollar, quantity demanded decreases by _%.
