Which of the following statements is correct?

*ALL are correct* The demand for flat-screen computer monitors is more elastic than the demand for monitors in general. The demand for grandfather clocks is more elastic than the demand for clocks in general. The demand for cardboard is more elastic over a long period of time than over a short period of time.

Refer to Figure 5-10. If rectangle D is larger than rectangle A, then

*ALL of these are correct* demand is elastic between prices P1 and P2. a decrease in price from P2 to P1 will cause an increase in total revenue. the magnitude of the percent change in price between P1 and P2 is smaller than the magnitude of the corresponding percent change in quantity demanded.

If a 40% change in price results in a 25% change in quantity supplied, then the price elasticity of supply is about

0.63, and supply is inelastic.
