Question

Calculate the midpoint price elasticity of demand between 80,000 and 100,000

Answer 1

Mid-point is the middle of the two endpoints.

80,000 and 100,000 is your end point, to get mid-point, add the two numbers together and divide by two

or (x + y)/2

IN this case, (80,000 + 100,000)/2

your answer is 90,000
