. With reference to the demand schedule in Figure 2.2 calculate the arc elasticity of demand between the prices of (a) 3 and 6, (b) 6 and 9, (c) 9 and 12, (d) 12 and 15, and (e) 15 and 18. 2. A city bus service charges a uniform fare for every journey made. When this fare is increased from 50p to 1 the number of journeys made drops from 80,000 a day to 40,000. Calculate the arc elasticity of demand over this section of the demand schedule for bus journeys. 3. Calculate the arc elasticity of demand between (a) 5 and 10, and (b) between 10 and 15, for the demand schedule shown in Figure 2.3. D 0 120 Quantity 5 15 Price 10 40 80 Figure 2.3 4. The data below show the quantity demanded of a good at various prices. Calculate the arc elasticity of demand for each 5 increment along the demand schedule.
