A

Percentage change in the quantity demanded of a certain good due to a percentage change in income.

35
Q

A

Cross Price Elasticity

36
Q

37
Q

When there few close substitutes available for a good, demand tends to be

A

relatively inelastic.

38
Q

A

complements.

39
Q

Price Elasticity of Demand is equal to

A

Percentage in Qd/ Percentage change in Qp

40
Q

If the market for a product is broadly defined, then there are ______________________ for the product and the demand for the product is relatively _________________.

A

few substitutes for the product and the demand for the product is relatively inelastic

41
Q

43
Q

This graph is likly showing

A

Unit Elastic- a change in price results in an equal change in demand

44
Q

This graph is likey showing an ____________ demand.

A

Elastic- Change in quantity demanded is larger than the change in price. If price changes a small amount, there is a larger amount of quantity demanded.
