Price elasticity of Y; no year

Suppose the demand function for a product is Q = p. Compute the point elasticity of demand at Q = 30. Then compute the arc price elasticity of demand over the interval Q= 40 to Q = 30; over the interval Q = 31 to Q = 30; over the interval Q = 30.1 to Q = 30. Comment on the pattern of these price elasticities.

Explain whether you agree or disagree with the following statement: An economist would classify a new automobile that does not start in cold weather as an inferior good. (Apologies for giving this question given the recent weather, but it IS a good question).

Does the quantity demanded increase or decrease with income?

Suppose the demand function for a product is Q = p. The good is currently selling for $5. Compute consumer surplus. Then compute the deadweight loss if the government imposes a tax of $2 on each unit sold.

Q=150-12P $5 90

Q=150-12P $5 90 $

Q=150-12P $5 90 $

Q=150-12P $5 $90 $

Q=150-12P $5 90 $12.5 $7 66

Q=150-12P $5 90 $12.5 $7 66 DWL=$24
