Suppose products A and B have demand and supply equations that are related to each other. If QA and QB are the quantities produced and sold of A and B, respectively, and PA and B are their respective prices, the table below shows the demand equations and the supply equations. Eliminate QA and qB to get the equilibrium prices. demand equations 9A =7-PA +1 + PB 9B = 26+ PA - PB supply equations - 5+ 6PA - 3PB 9A = - == QB-7-3pд+6PB The prices are PA = $| and PB = $ (Round to the nearest cent as needed.)

The demand and supply functions for three (03) goods are given as follows: Dx = 100-3Px+Py+3Pz Dy = 80+Px-2Py-Pz Dz = 120+3Px-Py-4Pz Sx = -10+Px Sy = -20+3Py Sz = -30+2Pz determineThe equilibrium prices and quantities of all three goods are? The government decides to: Impose a 25% Tax on X? Impose a 5 Rs /unit Tax on Y? Give a 10% subsidy on good z? Analyze the impact of each of these policies separately on equilibrium prices and quantities? Also calculate changes in consumer and producer surpluses, and amount of revenue earned by the government? Repeat this exercise when policies (a, b), (b, c) and (a, b, c) are jointly implemented. Which policy choice is best? Why? Provide theoretical justification (using diagrams) of all results obtained?

Next, plot the supply of ice cream using the orange point (square symbol). Finally, use the black point (plus symbol) to indicate the equilibrium price and quantity in the market for ice cream. g Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically. 24 Demand 20 16 Supply 12 MacBook Air per gallon of ice cream)

Suppose that the market for bottled water can be represented by the following equations: Demand: P = 10 - 2QDSupply: P = 1 + 0.5QSwhere P is the price per gallon, and Q represents quantity of purified water, represented inmillions of gallons of water consumed.a) Calculate the equilibrium price and quantity of bottled water.b) Concerned over high water prices after the winter storm, the government sets a priceceiling of $2.25 per gallon of water. What is the new quantity of water sold in themarket? Use supply and demand curves to illustrate your answer, showing both theoriginal equilibrium from part a) and the new quantity sold with the price ceiling.c) Calculate the producer surplus and consumer surplus at the initial equilibrium priceand quantity from part a).d) Calculate the new producer surplus and consumer surplus with the price ceiling frompart b).e) How does the total consumer and producer surplus in part c) compare to the totalconsumer and producer surplus in part d)? What…

1. The weekly demand (Qd) and supply (Qs) functions for a good X are given by:-Qd = 1000 – 5pQs = -400 + 15p, where P = Price per unit (R)(i) Draw the demand and supply curves on a graph and find the equilibrium priceand quantity (ii) If the demand function changes to 1200 – 5P, show the changes to part (i)above. (iii) Suppose a subsidy of R40 per unit is subsequently granted to producers ofgood X. Determine the new equilibrium price and quantity. (b) Use suitable examples to explain the likely effects of a price ceiling. (c) What do you understand by the ‘Substitution and Income effects’ of a change inprice of a good. (d) Elaborate on the factors influencing Price Elasticity of Demand (PED) and PriceElasticity of Supply (PES) of a good. 2. (a) Explain the concepts of Price Elasticity of Demand (PED), IncomeElasticity of Demand (YED) and Cross Elasticity of Demand (CED)(b) To what extent can PED be important to:-(i) a government, (ii) managers of hypermarkets ‘3.

The market demand for productXis given by: \[ Q_{d}=6-1 / 2 P \text { or } P d=12-2 Q \] The market supply for goodXis given by: \[ Q_{s}=-14+2 P \text { or } P s=7+1 / 2 Q \] whereP=price per unit andQis number of units. Draw a supply-and-demand graph with these curves. 1.) Using the line drawing tool, draw the supply and demand curves. Properly label your lines. 2.) Using the point drawing tool, plot the equilibrium point. Label your point 'E'. Note: Carefully follow the instructions above and only draw the required objects. The equilibrium price is$and the equilibrium quantity is unit(s). (Enter your responses as integers.) A per-unit excise tax is imposed on suppliers of productX, and the market supply with the tax is now given by: \[ Q_{s}=-19+2 P \text { or } P s=9.50+1 / 2 Q \] Using the graph on the right, show this supply curve. 1.) Using the line drawing tool, draw the new supply curve. Label your line 'S1​+tax'.1. Note: Carefully follow the instructions above and only draw…

-How has Covid-19 affected the market for gasoline?  Which of the main influences of supply and demand do you think were responsible for the price changes? (See textbook pages 90-91 and 97-98.) Be specific and explain why and how the “main influences” you chose had an impact on the gasoline market.

The annual demand for imported oranges is given by the following equation:QD = 600,000 − 30,000Pwhere P is the price per kilogram and QD is quantity of kilograms demanded per year.The supply of imported oranges is given by the equation:QS = 20,000P Calculate the following: ii. the amount of revenues collected

1. Suppose that a small, tropical country produces mangoes for domestic consumption and possibly for export. The national demand and supply curves for mangoes in this country are given by the following: P = 50 - M P = 25 + M (national demand) (national supply) where P denotes the relative price of mangoes and M denotes the quantity of mangoes (in metric tons). (a) Illustrate these relationships geometrically. What is the autarky price and quantity (b) exchanged? (c) Suppose that the world price of mangoes is 45. Will this small country export mangoes? If so, how many tons?

1.
