Question 1

Suppose that a store decreases the price of peanut butter from $4 to $3.9. As a result, quantity demanded increases from 220 to 250.

Using the mid-point elasticity approach, calculate price elasticity of demand.

Your answer should be expressed in absolute value terms.

 

Suppose that a store decreases the price of cereal from $4.4 to $3.8. As a result, quantity demanded increases from 220 to 260.

Based on this information, find the price elasticity, which you can use to classify the demand curve as price elastic, unit elastic or inelastic.
