Until recently, Dave's Donuts sold their premium chocolate-cornflake-cronut for $3.75, and they would sell 55 per week. Now, Dave has raised the price of the chocolate- cornflake-cronut to $4.25, as a result, they are selling only 45 per week. Using the midpoint rule, find the price elasticity of demand for the chocolate-cornflake- cronut at Dave's Donuts. [a]

Expert Solution
Step 1

When we will use the average percentage change in both quantity and price,then this is called the midpoint method for elasticity and is represented by the following 

Price elasticity (mid point )= Q ×(P1 +P2)P×(Q1 +Q2)
