Let one week's supply (S) and demand (D) functions for gasoline be given by p Upper D (q) equals 300 minus four-fifths q and p equals S(q) equals two-fifths q, where p is the price in dollars and q is the number of 42-gallon barrels. (A) On what interval is the quantity supplied below the equilibrium quantity?
Demand (D) | = | 300 - 4/5 q |
Supply (S) | = | 2/5 q |
Where, q = Equilibrium quantity | ||
At Equilibrium point, Demand (D) = Supply (S) | ||
Demand (D) | = | Supply (S) |
300 - 4/5 q | = | 2/5 q |
300 | = | 4/5 q + 2/5 q |
300 | = | 6/5 q |
q | = | (300*5) / 6 |
q | = | 250 |
Therefore, at quantity of 250 barrels. |

(2 points) Suppose D(g)-1932 and S(12q+1 are the demand and supply functions for a particular commodity. That is, q thousand units of the commodity will be demanded (sold) at a price of p D() dollars per unit, while q thousand units will be supplied by producers when the price is p S(q) dollars per unit. a. Find the equilibrium price Po where supply equals demand Answer: Po dollars per unit b. Compute the consumers' surplus at...
The demand function for a product is: Upper Q Superscript d Baseline equals 1 comma 600 minus 10 Upper PQd=1,600−10P, and its supply function is: Upper Q Superscript s Baseline equals 400 plus 5 Upper PQs=400+5P. The equilibrium price of the good is equal to nothing. The equilibrium quantity of the good is equal to nothing. From a figure showing the demand and supply curves of the good, the equilibrium price and quantity can be determined from the ▼ .
Using the supply and demand functions below, derive the demand and supply curves if Y = $55,000 and pc = $7. What is the equilibrium price and quantity of coffee? The demand function for coffee is Q = 8.5-p+ 0.01Y, where Q is the quantity of coffee in millions of pounds per year, p is the price of coffee in dollars per pound, and Y is the average annual household income in high-income countries in thousands of dollars. The coffee...
d) All UI WU UUUU 9) Suppose the demand and supply for cheese curds is given by the following equations where P is the price per unit of cheese curds and Q is the number of units of cheese curds: Demand: P = 15 - 30 Supply: P =Q+3 If the government imposes an excise tax of $4, what will be the resulting consumer price and producer price? 10) The figure below represents demand and supply in the market for...
The Demand and Supply functions, D (a) and S(9), for a particular commodity are given. Specifically, thousand units of the commodity will be demanded (sold) at a price of p= D (a) dollars per unit, while a thousand units will be supplied by producers when the price is p = S(q) dollars per unit. Find the consumers' surplus and the producers' surplus at equilibrium. D(q) = 65 - q'; $(a) = 12 + 2q + 5 O CS - $144,000;...
The demand and supply functions of a goods are given by:p=-4Qd + 120, p=1/2Qs + 28, where and denote the price, quantity demanded and quantity supplied respectively. Find the equilibrium price and quantity.
The demand and supply functions of a good are given by P= -5Qd + 80 P= 2Qs + 10 where P, Qd, and Qs denote price, quantity demanded and quantity supplied respectively. Find the equilibrium price and quantity graphically and algebraically. Show all work. If the government deducts, as tax, 15% of the market price of each good, determine the new equilibrium price and quantity. Show all work.
Your demand and supply functions are given by D: P=50-Q and S: P=10+3Q. Determine the market equilibrium price and quantity. If a price floor is put into place at P=30, determines the shortage or surplus, if any (think carefully). Draw a graph and show your calculations for full credit.
