3.Medium
When the price of a ticket changes from €15.00 to €17.00, weekly sales change from 1200 to 1100. Use the midpoint (arc) method to find the price elasticity of demand E.
P1 = €15.00P2 = €17.00Q1 = 1200Q2 = 1100
E =
4.Medium
When the price of a ticket changes from €40.00 to €38.00, weekly sales change from 100 to 110. Use the midpoint (arc) method to find the price elasticity of demand E.
P1 = €40.00P2 = €38.00Q1 = 100Q2 = 110

5.Hard
The demand for a product is Q = 400 − 4P, with P in euros. At which price P is total revenue as large as possible?
Q = 400 − 4P
P = €
6.Hard
The demand for a product is Q = 160 − 4P, with P in euros. Find the price elasticity of demand E at a price of €28.
Q = 160 − 4PP = €28
E =
