A railway company raises ticket prices by $10\%$ for journeys between 06:00 and 09:00, which leads to a $2\%$ fall in demand. After 09:00 it cuts ticket prices by $5\%$, causing demand to rise by $7\%$. What is the price elasticity of demand in response to these price changes?
- Aelastic between 06:00 and 09:00; elastic after 09:00
- Belastic between 06:00 and 09:00; inelastic after 09:00
- Cinelastic between 06:00 and 09:00; elastic after 09:00
- Dinelastic between 06:00 and 09:00; inelastic after 09:00
