increase

0.64

Explanation:

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price  

Abe's elasticity of demand is elastic because it has a value greater than 1.

if quantity demanded decreases, it means that price must have been increased.  this would lead to a decrease in total revenue

If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.  

Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one

Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.  

Infinitely elastic demand is perfectly elastic demand. Demand falls to zero when price increases  

Perfectly inelastic demand is demand where there is no change in the quantity demanded regardless of changes in price.
