Could someone explain the easy way to find the partial derivative in these problems? Suppose the demand equation is: Q = 120 - 0.75p. What is the price elasticity of demand if the price is $60 per unit and output is 75 units? The price elasticity of demand is (Enter a numeric response using a real number rounded to two decimal places.)

(В) The British Automobile Company is introducing a brand new model called the "London Special." Using the latest forecasting techniques, BAC economists have developed the following demand function for the "London Special": Qр 3 1,200,000- 40P a) What is the point price elasticity of demand at prices of (a) $8,000 and (b) $10,000? b) Is it Elastic, Unit Elastic or Inelastic, Explain why?
According to studies undertaken by the U.S. department of agriculture, the price elasticity of demand for cigarettes is about +0.5. Suppose a major brokerage firm advised its clients to buy cigarette stock under the assumption that, if consumer income rise by 50 percent as expected over the next decade, cigarette sales would double. Based on the fundamental economic principles on income elasticity of demand, a reasonable reaction to this investment advice would be?
The quantity demanded x each month of Russo Espresso Makers is 250 when the unit price p is $150; the quantity demanded each month is 1000 when the unit price is $120. The suppliers will market 750 espresso makers if the unit price is $50. At a unit price of $80, they are willing to market 3000 units. Both the demand and supply equations are known to be linear. (a) Find the demand equation.p = (b) Find the supply equation.p = (c) Find the equilibrium quantity and the equilibrium price. equilibrium quantity units equilibrium price $

Price & Demand In economic theory, we let z represent the number of items (called demand) a supplier will produce if the price of the item is p. For a particular item, if the price is $10 per item, then the demand is 577 items. However, if the price is raised to $33 per item, then the demand decreases to 393 items. Using this information, find the demand equation as a function of the price p? r(p)
