Answer 1

Midpoint elasticity measures the average change in demand and price, rather than the change at the endpoint.

Here is how the midpoint formula looks: [(D2 minus D1) divided by (D2 plus D1, then divided by 2)] divided by [(P2 minus P1) divided by (P2 plus P1, then divided by 2)]. Note that the denominator is an average because the denominator sums get divided by 2.
