QPD1000€5.001060€4.50

When the price of a ticket changes from €5.00 to €4.50, weekly sales change from 1000 to 1060. Use the midpoint (arc) method to find the price elasticity of demand E.

P1 = €5.00P2 = €4.50Q1 = 1000Q2 = 1060
E =
4.Medium
QPD1 000€4Q2​P2​ (−15%)ΔR = ?

A product sells 1 000 units per month at €4. Its price elasticity of demand is −2.5. The firm changes the price by −15%. Assuming %ΔQ = E·%ΔP, by how much ΔR does monthly revenue change?

P1 = €4Q1 = 1 000E = −2.5%ΔP = −15%
ΔR = €
5.Hard
QPDQP = ?

The demand for a product is Q = 200 − 4P, with P in euros. At which price P is total revenue as large as possible?

Q = 200 − 4P
P = €
6.Hard
QPDQP = ?

The demand for a product is Q = 800 − 10P, with P in euros. At which price P is total revenue as large as possible?

Q = 800 − 10P
P = €

Answer key

  1. 1. E = −0.4
  2. 2. E = −0.2
  3. 3. E = −0.5534
  4. 4. ΔR = 675 €
  5. 5. P = 25 €
  6. 6. P = 40 €
