Suppose that a store decreases the price of cereal from $4 to $3.9. As a result, quantity demanded increases from 190 to 270.

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

Your answer should be expressed in absolute value terms.

Hint

Box 1: Enter your answer as an integer or decimal number. Examples: 3, -4, 5.5172
Enter DNE for Does Not Exist, oo for Infinity

Suppose that a store decreases the price of cereal from $4.4 to $3.5. As a result, quantity demanded increases from 210 to 270.

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