If the price elasticity of demand for a product is 2.5, then a price cut from $2.00 to $1.80 will:
A. increase the quantity demanded by about 2.5 percent.
B. decrease the quantity demanded by about 2.5 percent.
C. increase the quantity demanded by about 25 percent.
D. increase the quantity demanded by about 250 percent.

Answer:

c

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.

Percentage change in price = (1.8 - 2) / 2 = -0.10

2.5 = percentage change in quantity demanded / -0.10

percentage change in quantity demanded = 0.10 x 2.5 = 0.25 = 25%

Because there was a decrease in price, demand would increase by 25%
