Midpoint formula for elasticity math. Using the midpoint method to calculate the price elasticity. The study of economics uses this calculation to find the coefficient of elasticity either demand or supply by measuring the average of the two points. Find the midpoint p between 1 2 and 3 6. Percent change in quantity q 2 q 1 q 2 q 1 2 x 100.
As mentioned before we can avoid this problem by using the so called midpoint method. The midpoint formula is a formula used to find the halfway point between two coordinates on a graph. The midpoint formula is used to locate the point at the middle of the imaginary line. Midpoint elasticity 100 550 10 25 0 18 0 4 0 45.
The equation may be complex for some because of all the different numbers involved but the process is relatively straightforward as long as each step is broken down. The midpoint formula for elasticity is the percentage change in quantity demanded divided by the percentage change in price. Try to imagine two points on a graph and an imaginary line that connects them. Q 1 10 p 1 100 q 2 30 p 2 150 by signing up you ll get thousands of.
