Given the demand equation Qdx = 50 - Px, compute the own price elasticity of demand for x when the old price is 10 pesos and the mew price is 15 pesos

A good's demand is given by: P = 775 - 2Q. At P = 127, the point price elasticity is: Enter as a value (round to two decimal places if necessary).

A good's demand is given by: P = 497-2Q. At P = 106, the point price elasticity is: Enter as a value (ROUND TO TWO DECIMAL PLACES).

Suppose demand is linear: Qd=a-bP We know that the price elasticity of demand is -0.5, quantity of demand Qd=100, price P=10, then: a=200,b=10 a=200, b=-10 a=150, b=5 a=50, b=-5

A good's demand is given by: P = 860 - 4Q. At P = 55, the point price elasticity is: Enter as a value (round to two decimal places if necessary).

If in response to a 6% increase in price quantity supplied increases by 9% what shall be the de- gree of the supply elasticity

Worldwide annual sales of smart phones in over a five-year period were projected to be approximately q=-10p+4440 million phones at a selling price of $P per phone. Obtain a formula for the price of elasticity of demand E. In one particular year the actual selling price was $271 per phone. What was the corresponding price elasticity of demand? Use your formula for E to determine the selling price that would’ve resulted in the largest annual revenue. What, nearest to the nearest 10 million, would have been the resulting annual revenue?

The extended demand function of good X is: QDX = 1400 20 PX - 10 PY + 0.1 M where: QDX = quantity demanded of good X PX Price of good X PY = Price of related good Y (related in consumption to good X) M = Average consumer income. Fix the following variables: PX = 50 M = 10,000 Assume: PY changes from $50 to $80 What is the cross-price elasticity of the demand of good X with respect to PY [Use the arc elasticity formula.] a. -0.69 b. C. d. -0.87 Based on your answer to the previous question, goods X and Y are: b. 0.69 a. inelastic C. 0.87 d. complements inferior substitutes

Given the demand function QD = 18 − 3P, answer the following ques-tions.(a) Calculate the price elasticity of demand if the price increases fromP1 = 2 to P2 = 5 using the midpoint method.(b) Calculate the point price elasticity of demand at QD = 13.5.(c) At which price/quantity is demand unit elastic?(d) At which price/quantity is demand perfectly elastic and perfectlyinelastic, respectively?
