The supply and demand curves for a product are given by the following equations: ? = ??? + ? and ? = ??? + ? where ?? is the quantity supplied, ?? is the quantity demanded, ? is the price of the product, and ?, ?, ? and ? are constants. Part A Give a definition of supply and demand curves and explain what is meant by equilibrium price and equilibrium quantity. Give an explanation in context, considering the equations above and supporting your explanations with the use of appropriate graphs. State the range of values of the parameters ?, ?, ? and ? giving reasons based on supply and demand economic theories. Part B The equation of the demand function for luxury sparkling wine is given by ?? = 1520 ? 5? where ?? is the number of bottles demanded weekly and ? is the price per bottle in euros. From a market analysis was found that: ? The price of each bottle increases by ? 2.65 for every extra 10 bottles produced, and ? The number of bottles produced is the same as the number of bottles bought when their price per bottle is ? 184. Sketch both the supply and the demand curve for sparkling wine on the same graph labelling the equilibrium point and any intersections with the axis. You need to label each axis and give the equation for the curves in the form ? = ?(?). You also need to show all your working and give full explanations in your own words. Part C The supply and demand curves given in Part B, determine the effect on the market equilibrium if a fixed tax of ? (10 + ?) is introduced on the production of each bottle of wine. Here ? is the last digit of your ID number. I need to use appropriate graphs to represent this situation, show all your working and provide full explanations in your own words and in context. You also need to explain how much the consumer and the producer will pay more due to the introduction of this new tax.

The supply and demand curves for a product are given by the following equations: P=aQs+b and P =CQo+d where Q; is the quantity supplied. Q is the quantity demanded, P is the price of the product, and a,b,c and d are constants. Part A Give a denition of supply and demand curves and explain what is meant by equilibrium price and equilibrium quantity. Give an explanation in context. considering the equations above and supporting your explanations with the use of appropriate graphs. State the range of values of the parameters a, be and {1 giving reasons based on supply and demand economic theories. Part B The equation of the demand function for luxury sparkling wine is given by 01) = 1520 5P where 01:: is the number of bottles demanded weekly and P is the price per bottle in euros. From a market analysis was found that: - The price of each bottle increases by 1E 2.55 for every extra 1D bottles produced, and - The number of bottles produced is the same as the number of bottles bought when their price per bottle is 184. Sketch both the supply and the demand curve for sparkling wine on the same graph labelling the equilibrium point and any intersections with the axis. You need to label each axis and give the equation for the curves in the form P = Q). You also need to show all your working and give full explanations in your own words. Part C Using the supply and demand curves given in Part B, determine the effect on the market equilibrium if a xed tax of (10 + N) is introduced on the production of each botlfe of wine. Here N is the last digit of your ID number. You need to use appropriate graphs to represent this situation. show all your working and provide full explanations in your own words and in context. You also need to explain how much the consumer and the producer will pay more due to the introduction of this new tax
