Doing The Numbers: Midpoint

- Our task is to calculate the price elasticity of demand using the midpoint formula.
midpoint
elasticity | = | (Q2 - Q1)
(Q2 + Q1)/2 | ÷ | (P2 - P1)
(P2 + P1)/2 |
- The values for this formula are P1 = $2.49, Q1 = 5,447 tacos, P2 = $1.99, Q2 = 6,608 tacos.
midpoint
elasticity | = | 0.19 ÷ - 0.22 | = | - 0.86 |
- This value - 0.86 indicates that the a one percent decline in the price of Tacos results in a 0.86 percent increase in quantity demanded.
