Answer:
B. a small percentage decrease in price produces a larger percentage increase in quantity demanded and total revenue increases.
Explanation:
Elasticity of demand measures the responsiveness of quantity demanded to changes in price.
Elasticity of demand = percentage change in quantity demanded / percentage change in price
Demand is elastic if a small percentage decrease in price produces a larger percentage increase in quantity demanded . Total revenue would increase because the percentage increase in Quanitity demanded exceeds the percentage decrease in price.
If demand is elastic, a small percentage increase in price produces a larger percentage decrease in quantity demanded and total revenue increases.
Here, total revenue falls because percentage decrease in price exceeds the percentage increase in price.
Demand is inelastic if a small percentage decrease in price produces a smaller percentage increasein quantity demanded.
Demand is perfectly inelastic if the quantity demanded remains the same regardless of level of price.
