Answer :
Answer:
Christy's demand for blackberries is elastic.
Explanation:
Christy purchases blueberries, blackberries, and strawberries. When the price of blackberries rises to a small extent, Christy will instead purchase strawberries or blueberries.
This shows that the demand for blackberries is elastic. Elastic demand refers to the situation when a small change in price causes the quantity demanded to change to a great extent.
