A demand function is given by the equation Q = 112 – 3P.
Suppose the price is P = 15.
At this price, find the price elasticity of demand. USE THE POINT SLOPE METHOD to find this elasticity. Round your answer to the nearest tenth.
Answer
price elasticity of demand=(dQ/dP)*Q
dQ/dP=-3 ............. first differentiation of demand function
P=15
Q=112-3*15
=67
price elasticity of demand=(-3)*(15/67)
=-0.671641791
=-0.67
the demand is inelastic as the elasticity of demand is above -1.
A demand function is given by the equation Q = 112 – 3P. Suppose the price...

Suppose that demand is given by the equation: Qd 180-3P And supply is given by the equation: Qs P-20 Question Using the midpoint formula, calculate the elasticity for demand Round your answer to 2 decimal places) 2.43, and elastic @ 0.24, and elastic o 2.43, and inelastic 0.24, and inelastic
Given the demand function q = function. – 0.06p? + 3p find the elasticity E = Preview Use the elasticity function to determine the elasticity of demand when the price is $11.00 E(11) = Preview At this price, we would say the demand is: Inelastic Unit Elastic Elastic Based on this, to increase revenue we should: Keep Prices Unchanged Lower Prices Raise Prices License Points possible: 5 This is attempt 1 of 5.
1. Given the demand function Q = 500 - 3P - 2P, +0.01Y where and P denote quantity and price of the good, Y is income, and price of an alternative good. is the a) If P=20, PA = 30, and Y= 5000, find (i) the price elasticity of demand (ii) the cross-price elasticity of demand (iii) the income elasticity of demand b) If income rises by 5%, calculate the corresponding percentage change in demand, Is the good inferior or...
. Suppose the Demand for coffee is given by: Q=25-3p and the current market price is $3. Find the Consumer Surplus (CS). (3pts
Suppose the market was made up of two demanders. Demander 1 has a demand function given by: qp = 100 - 2P. Demander 2 has a demand function given by: qp = 250 - 4P. The horizontal summation of these two demand functions will, when graphed, have a kink (point where the slope changes). Determine the price associated with the kink in the total demand function. (Do not include a dollar sign in your response. Round to the nearest 2...
