A 20 percent decrease in the price of breakfast cereal leads to a 30 percent increase in the quantity of cereal demanded. As a result:A. total revenue will decrease. B. total revenue will increase. C. total revenue will remain constant. D. the elasticity of demand will increase

B

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

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

Price elasticity = 30% / 20% = 1.5

Demand is elastic. If price is reduced, the quantity demanded would increase and total revenue would increase
